I used to get pretty good life out of my stock bionic battery. I updated the OTA update early today and since then the battery level has been going down at almost 10% every 30 - 40 mins. Following is the list in my battery usage queue. This is after I did a system reset and left my phone without any new apps (except for facebook).
Display 30%
Android System 17%
com.motorola.contacts 12%
Android OS 9%
com.motorola.home 8% ....
I am planning to charge it to 100% and then see how it behaves. Will keep this thread posted with stats from my phone.

I can't remember where I saw the comment, but another Xoom user mentioned that his handwriting application(s) seemed to degrade in performance the longer he used them (per reboot, I believe). Until today, I thought I was imagining it, but the same thing seems to be happening to me. I was taking notes with Writepad and about one-half hour into the meeting I experienced significant lag between strokes of the stylus and appearance on the screen, and I needed to revert to the keyboard. It's happened with other handwriting applications as well.

I have noticed much shorter battery life after update to 3.1.
Nothing has changed in terms of battery consumption.

So, I had horrible battery performance after the update. I figured I would do a cache wipe. Normally this erased battery history, but not this time. The gap is during the wipe. Notice the average slope before and after
I wish they could push an update that doesn't require this crap, but its never happened.

I have heard many conflicting versions of the optimal way to maximize the battery's life. It would be great to get some clarity from the experts.
1. Can you charge the phone at any time or should the battery be drawn all of the way down?
2. Once the battery is fully charged, should it be immediately disconnected from the charger, or is it OK to leave the charger attached?
3. if you are using the device, and it is below full charge, is it OK to have it charging while you are using it?

I bought the device few days ago and on very same day updated to Android ver. 3.2. I use internet over my home Wifi and have a Netgear - WGR614 router. The browsing speed is very very slow and most sites dont open.The signal strength shown in xoom is - (-105 dBm 3 asu).Is this a issue with Android 3.2 update or my home wifi is weak? Would i be able to reset the tab to the original version?

I would like to know what other users of the N900 think of the battery.I have only had a my device a few days and I can only get less than a day's use out of the battery.This is with the Wifi switched off (I mainly use the 3.5G). I do very little internet browsing. I just leave the phone on my desk, check my emails occasionally. Is this normal performance ? Does anyone get more than a day's use?

Ok so I have a 3GS and used to have decent battery performance, losing maybe 3% over night. Well I jailbroke and like a lot of people had way worse battery, losing up to 10% over night. I did a complete restore and re jailbroke and it seemed a little better.
Well I was charging the phone tonight by USB to my computer. I checked it and saw it was at 99%. I went to watch a show and came back and now was it was at 96% still plugged in and charging. I then rebooted the phone and it was at 98%. Anyone know what the reason for this could be and a solution?

I recently bought a Nokia 6700 slide and it comes in a package with a BL-4CT battery 860 mAh, 3.7 V and 3.2 Wh. How the battery performance is poor ( keep about two days), I thought to replace it with a BL-5CT battery 1050 mAh, 3.7 V and 3.9 Wh, or BL-5J battery 1320 mAh. Or even a BP-4L battery 1500 mAh ( that do not know if it fits ).Can I improve in this way life time during the talk and standby?

I like having my phone jailbroken but my proximity sensor is a big enough issue to warrant updating. That is of course if the update truly fixes it.Anyone care to share their experience so far after the update?

Ever since I initially charged my XOOM the battery indicator shows 100% full, never shows any discharge & just shuts down when the battery is flat with no warning, any ideas, still under warranty.

I've finally decided to do I just got the customary 14% charge warning, and so I open up Settings > Applications > Battery Use and Gallery is listed as consuming 44%.This is crazy, especially since I haven't even USED Gallery since the last time I charged (which was done following an auto-power down fwiw).I thought about going into Advanced Task Killer and seeing if I could change the settings to make it really aggressive against Gallery, but it informs me that all "green labeled" tasks are "front apps" that can't be killed directly. Manually killing it gives no joy -- the damn thing is right back in the list like some annoying Warner Bros. cartoon character the next time I open ATK.
I used to brag about the Xoom's battery life, but it's getting so I can't any more.I have not yet sent in my Xoom for the 4G upgrade; currently running build number HTK75D, but this has been an issue long before this build.

Is there an app that can accurately measure the condition of the battery similar to software in notebook PCs? My battery is coming up to 15 months old and I notice this past week it doesn't seem to be as good at holding a charge.
Has anyone used Motorola Service to replace the battery yet?

Just got my upgraded XOOM back a few days ago, and I've noticed that the battery life is far, far worse than it was before I sent it away. I mainly use my XOOM for reading ebooks, so I nearly always have airplane mode on. Before the upgrade, I could go several days, sometimes even a week before having to charge the battery, even with occasional excursions outside airplane mode.
However, after the upgrade, I can have the XOOM fully charged, in airplane mode, read for an hour just before going to sleep, shut off the screen, and wake up the next day with 60% battery remaining, as opposed to being in the 90-95% range before the upgrade.
The battery usage app shows 87% screen, 11% idle, 3% drmserver. One strange thing I've noticed is that under Settings > About tablet > Status, I see this:
Network: Searching for service
Signal strength: -120dBm 16 asu
Mobile network type: Unknown:0
Service state: Radio off
Roaming: Not roaming
Mobile network state: Disconnected
Why would it be searching for service in airplane mode? Did something break in 3.2.2?
So my questions are:
1. Is anyone else experiencing the same symptoms as above (reduced battery life after upgrade, screen showing most usage)?
2. Is there any way for me to downgrade to 3.2 in order to see if that helps? I don't care if that disables 4G, since I'm not in a 4G coverage region.

I have a completely standard xoom and noticed that its getting really warm even when in idle. It started happening last week. I thaught it might be an app I downloaded so uninstalled all new apps. Still getting warm and bad battery performance. So I done a full factory reset and still getting the issue.

Is there something one can do so that the Xoom does not shutdown automatically when battery level reaches 20%? I am on ICS 4.04.

I have had my zoom for 3 or 4 months,maybe longer, and I notice that my battery life is slowly decreasing in time available before having to re-charge. I bought my xoom as reburbished, but understood it had the same warranty as if new bu Motorola. Initially I could go 2-3 days without charging, just by letting the unit go to sleep. Now it only lasts for a day or day in a half.

I have noticed that the WIFI- Network Notification ( Notify me when an open network is available) is ticked after the 3.1 updateI am presuming this means its always looking for a open network and chewing up power doing so.To save some battery, and alien networks, untick the boxUnless you ok with open network hunting and shorter battery life.
