If the device does not turn on, follow these steps:

1. Inspect the device and the battery for any signs of physical or liquid damage. If found, please call HTC for an out-of-warranty repair.
2. Press and hold the Power key for 3-5 seconds to verify that the device will not turn on.
3. Remove the battery and check the contacts.
   • If there is residue found, clean with a soft dry cloth, re-insert the battery and retest.
4. Attempt to charge the device/battery.
   • Charging is indicated by a solid amber Notification LED in the top left. As the battery is being charged while the phone is on, the charging battery icon is displayed in the status bar of the Start screen. After the battery has been fully charged, the Notification LED shows a solid green light and a full battery icon displays in the status bar of the Start screen.
   • If the device status light does not stay solid Amber* or solid Green when the device is plugged in, try the following:

·   Plug the charger into a different power outlet.

·   Try a different device charger.

·   Try a different battery.

* If the battery is completely dead or critically low, the charging LED will blink Amber for a few minutes and then turn to a solid Amber. At this point, the device can be powered on.

5.      Ensure that the Charger/Data Cable is the one intended for the device by HTC.

·         Use of non OEM chargers/data cables can cause your screen to become unresponsive (due to the power being allocated to charging the task, and not the screen).

·         HTC can only guarantee items such as chargers that have been made, made for and certified by HTC.  Our chargers have been tested and passed strenuous quality and safety regulations, and it is recommended you only use HTC chargers with your phone. You must be very careful when using electrical appliances; using products that have not been tested properly or that have not been tested at all could cause your phone to malfunction, or even in extreme cases, could injure you.

1. After the battery is fully charged, attempt to Power the device on again.
2. Rule out 3^rd party application interference by removing applications recently downloaded and installed from Market: Market>Menu>Downloads. Touch on the items(s) to be removed and follow the onscreen prompts. Restart the device to complete the removal.
   • Note: Do not re-install the program and flag it as harmful to the device if the issue is not seen after the application removal.
3. If the problem is still present, the device will need to be Hard Reset; this will undo everything that has been done to the device and restore it back to factory setting.
   • The user will need to back up any data they do not want to lose before performing the Hard Reset.
   • From the Home Screen, select Menu>Settings>SD & phone storage>Factory data reset and follow the onscreen prompts.
   • If the issue still remains, the device can now be considered for an Exchange.

Tips for battery conservation:

There are different features such as watching YouTube, listening to music, programs running in the background, using Wi-Fi and Bluetooth®, constantly synchronizing e-mail and/or using Live Wallpaper that can drain the battery quickly.

To improve battery life, refer to the following information:

1. When your device is not in use, press the Power button to switch off the screen.
2. Select a shorter idle time before the phone screen switches off and lower the screen brightness. To do this, press Home>Menu>Settings>Display and adjust the Screen timeout.
3. Use the AC adapter to plug your device into an external power outlet whenever possible.
4. Turn Bluetooth and Wi-Fi off when you are not using it.

·         Home>Menu>Settings>Wireless & networks

·         Uncheck both Wi-Fi and Bluetooth

1. Change the frequency for which your applications are synced.

Home>Menu>Settings>Accounts & sync

Select which email account or application you want to change, and then adjust the Update schedule settings.

1. Disable the vibration feedback with the keyboard, Home>Menu>Settings>Language & keyboard>Touch Input>Text input and uncheck Vibrate when typing.
2. Disable the Vibrate option for Ringtones & Sounds: Home>Menu>Settings>Sounds and uncheck Vibrate.

Hi,

I have a 2 weeks old HTC Inspire. I have completed all the "Tips for battery conservation". Still the battery is very poor. My usage of the phone is very low and I don't browse a lot. I still have to charge "twice" a day. There is no leakage in the battery.

This is really bad. Any alternatives please? Otherwise I have to return.

Hi,

I only have to charge mine once a day (unless I have been streaming Pandora or watching alot of YouTube).  Perhaps the issue is really with the battery in itself and not the device? There are apps availble in Market that can also help manage battery life (like Juice Defender as an example); be sure to read the reviews for market apps to see what others have to say about them.

Hi Lee,

I have a new phone. Still doing basic stuff. No streaming.

Issue is with the battery and not just for my inspire phone. You can see the posts here and also on the internet. I have tried all the suggestions, but still very poor battery performance.

I'm so frustrated- I loved my HTC Inspire for a day and the second day, the battery lasted only a few hours. If I have a full charge before I leave for work, my phone is dead by the end of the day. This is after sitting idle all day, no use. I've tried all the battery-saving tips. Bottom line is it's unsafe. I can't count on being able to go for a long walk an have the battery not run down even if I don't use it. If I don't find a solution in a few days it goes back and I go back to an Iphone.

Not sure if you have downloaded "Advanced Task Killer" app on your phone or not but it helped me.  I had to recharge every night but with this app, I only charge it every other day with four emails with continuous polling.  BTW, it seems that Android is the culprit here..

I am using my Inspire as my only phone. I have cancelled my land line account. The battery on this phone is just unacceptable, but my question is this:

Should I only charge my phone when the battery runs out of charge or even down to 10% or so, or can I use my phone like my old cordless land line phone and keep the phone in a charging cradle all day, returning it there after I use the phone regardless of battery strength?

Also, there are two cradle chargers with a spare battery charging slot available at HTCPedia. Are these official chargers for the Inspire? Can these be used as the main phone charger? I don't know what company manufactures these cradle chargers.

Thanks to whoemever responds.

@ Jersey Jeepster:

Most manufacturers of Lithium Ion batteries suggest that you charge the battery fully when you first put it in service.  Following the first charge, run it all the way down to very low charge (preferably 0% but 3-5% works), then recharge it fully.  Repeat this cycle twice.  Then during normal use, discharge to mid-low point (20% to 50%) and then recharge.  Once per month, deep cycle the battery (close to zero then back to full charge).  L-ion batteries do not have "memories" like the old NiCad or NmH batteries, so they are much more forgiving no matter how you use them. 

Charging cradles are fine, but you shouldn't leave the battery on the charger all day "cooking" like you would a cordless phone; but having the phone in a charging cradle to recharge it back to 100% every day is fine.

The only "official" charger comes with the Inspire at purchase, but most chargers that provide the correct voltage/wattage will work.  The battery will always charge faster when attached to a charger rather than connected to a USB port on a computer, since most USB ports don't deliver the wattage that a dedicated wall or mobile charger will provide.

I am traveling to Ireland in a couple of weeks. I know I need an adapter in order to plug in my HTC Inspire, but I understand I also need a transformer of some sort in order to not burn it to a crisp. Can you give me guidance on this?

Thanks.

I am traveling to Ireland in a couple of weeks. I know I need an adapter in order to plug in my HTC Inspire, but I understand I also need a transformer of some sort in order to not burn it to a crisp. Can you give me guidance on this?

Thanks.

The standard voltage in Ireland and most of Europe is 220v to 240v at 50Hz.  If you look on your charger that came with the Inspire, it will show the input voltage that it will handle.  My charger says 100v-240v and 50-60 Hz.  As long as your charger has this range, you don't need a transformer or power adapter.  You will need a plug adapter, since the wall sockets (receptacles) in Ireland and most of Europe have a wider dimension from prong to prong and the prongs are circular rather than rectangular that we use in the U.S.

Also, make sure you call AT&T and get an international calling plan and a data plan for Ireland.  If you don't, the phone calls get very expensive, very quickly.  Calls are typically $1.00/minute and data can run up several hundred dollars in a short time.

Thanks.Mine is the same (sorry, since this droid doesn't have a "box," I didn't realize that the plug itself is a charger. I thought it was just an adapter.

I do plan to check on the calling plan and also on renting a phone over there, or getting a separate SIM card. Will take any advice anyone has on those options.

I'm thinking of buying a Solar charger for the phone so it never runs out.  What is the max power consumption of the phone?  I'll need this information to buy the correct Solar charger.  It's obvious that the standard Solar charger will not keep up with this phone.

In addition to HeavenLee's steps:

Home>Menu>Settings>Wireless and Networks>Mobile Networks> Uncheck 'Enable always-on mobile data.' You'll probably never see a difference in data connectivity and you will save battery

Home>Menu>Settings>Location Uncheck GPS if you are not navigating. There is a widget to turn it off/on you can add to the home page too.

Home>Menu>Settings>Display>Screen Brightness Make sure it is automatic or at least not all the way up. 

Don't auto kill applications. Get rid of Advanced Task Killer, Task Manager, etc. If you want a task manager program written by people who know how Android works try Watchdog Task Manager Lite. Excessively killing applications, which are normally just cached images in memory to help speed the launching of recently used and commonly used tools, will cause data corruption and cause the battery to drain. Only kill Market apps, and only kill them if they are malfunctioning. Watchdog will show you if they are.

I have enjoyed reading many suggestions about the battery problems.  Today I received an e-mail from HTC with more ideas.  Some have been suggested before.  Hope it helps.  Do they work?  Haven't tried them yet.

From HTC:

1. Lower screen brightness. From the Home screen, press Menu > Settings > Display > Brightness. Slide the brightness switch [to the left to lower the brightness], or check the Automatic brightness box to let the device use its sensors to adjust the screen according to the ambient light.
2. Turn off WiFi, GPS, and Bluetooth when you don't need them.
3. Disable WiFi network notifications. Menu > Settings > Wireless & networks > WiFi settings. Uncheck the Network notification box.
4. Disable "always on" mobile data. This is one of the biggest battery savers. Menu >Settings > Wireless & networks > Mobile networks > uncheck the box at Enable always-on mobile data.
5. Turn off background data. Menu >Settings > Accounts & sync > Uncheck the Background data box so that applications cannot sync, send, and receive data whenever they want to.
6. Lower the screen timeout interval. Menu >Settings > Display > Screen Timeout.
7. Manually turn off the screen when not in use.
8. Turn off auto-sync. Menu >Settings > Accounts & sync > uncheck Auto-sync.
9. Change auto-sync frequency (Weather, News, Stocks, Twitter, etc). If you don't want to turn off auto-sync, you can adjust how frequently data is retrieved/updated. The settings vary depending on the app (and some don't offer the setting at all), but it's generally found in the same place. Menu >Settings > Accounts & sync. Tap the account you wish to change sync frequency on > Account settings > Update Schedule. Change according to your requirements.
10. Disable wireless network location services when not needed. Menu >Settings > Location > Tap Use wireless networks to disable using wireless networks. Please keep in mind that this needs to be enabled if you want to see and/or use your location in apps like Maps.
11. Turn off window animations. Menu >Settings > Display > Animation > No animations.
12. Don't use a live wallpaper.
13. Use a dark wallpaper.
14. Change WiFi sleep policy. This may sound counter-intuitive, but leaving WiFi on when the device isn't being used and the screen is off is actually better than letting it sleep. When WiFi sleeps, 3G /4G wakes up to sync, get email, and retrieve other data. 3G will eat up more battery than WiFi. Menu >Settings > Wireless & networks > WiFi settings > Menu > Advanced > WiFi sleep policy > Never.
15. Monitor your running services. Menu >Settings > Applications > Running Services. From this location you can view what your device is doing and manually stop certain running activities by tapping them.
16. Choose your home screen widgets carefully. Widgets that need access to the internet to update can suck up a lot of juice if not managed well, so choose them carefully and set their sync/update frequencies to a reasonable interval.
17. Disable notification lights. This may not be practical if you're someone who really needs/wants to know when something happens on your phone when you're not looking. Menu >Settings > Display > Notification flash > uncheck all the boxes.
18. Turn off phone vibration. Menu >Settings > Sound > disable Phone vibrate.
19. Turn off audible touch tones. Menu >Settings > Sound > disable Audible Selection > Tap Audible touch tones and select Off.
20. Turn off haptic feedback. Menu >Settings > Language & keyboard > Touch input > Text input > disable Vibrate when typing. You can disable haptics in other areas of the system. Menu >Settings > Sound > disable Vibrate feedback.

Thank you so much this was very helpful.  What web site can i get this so i can print out my own copy. They would not let me copy and paste your article
