[Q]Android battery life ? - TouchPad Q&A, Help & Troubleshooting

My Touchpad still with CM9 Alpha 0.5, the battery drains really fast during sleep ~30%ish per day with just sleep. I keep a close eye on what app is running and turn wifi off when screen is locked. But it does not help much.
Is it improved now? or any patch will do the trick?

Well first of all, I would update to Alpha 2, or the nightlies, or another ROM like AOKP. Battery has been something that is constantly getting improved.
Also, try turning it into Airplane mode and seeing if the drain is still significant. If it is, then its an app that is running constatnly and should be stopped. If it isn't, then its probably either an app that uses the network constantly or an email client or something.

There's also Rohan's tweaks, which work specifically for Alpha2, as well as all of the nightlies, that allow for a lot of battery tweaks and adjustments.
But again, upgrade to at least Alpha2, and you'll see a LOT of improvements.

[ROM] CM Nightlies Report (Progress Towards 6.1.0)

The old thread filled with sparse reports of Cyanogen Nightly release experiences has gotten old in the tooth. As we approach the release of 6.1.0, I feel it necessary to start fresh and record configurations (dates, kernel's, etc) with details that have the potential to benefit us all.
I am currently running the #169 nightly and an underclocked kernel (shooting for battery life at the moment), and have run into no stability issues thus far. This includes use of both wireless and bluetooth features.
Please reply with your positive or negative take on CM nightlies for the Incredible Build #100 or newer. Thank you!
Anecdotal Reports for 169:
-Video camera functions, Infinite focus only
-LEDs function as expected. Please remember Pule under your audio settings
-Stock kernel performs VERY well, however invisibleKs may improve your mileage

Can you verify that the built in wifi tethering works (using adrenylynes kernel)? if that doesn't, what about the wifi tethering app, and if it works, what version are you running, pre9?
I ran nightly 9/19 starting last night until now. The email FC problem seemed fixed from the 6.0.2 but i would get random restarts and incredilight would FC alot.
Cant wait for 6.1
i'd recommend using the HTC flashlight apk.. it works without the sense framework (works with cm6).
you can grab it from the themes/apps forum.

Unless I found the wrong post, the com.htc.flashlight.apk that was ported over from the Desire 2.2 Rom does not use the LEDs, but uses the screen instead. That is pretty gay.

I'm not sure about CyanogenMod and other AOSP ROMs, but the HTC Flashlight included in froyo uses the LEDs

I am on 9/19 and I'm happy to announce that my Gallery and Music Player can detect pictures and music on BOTH the eMMC and microSD.
However, Gallery still doesn't set pictures as wallpaper.
Running King's kernel but about to switch to Adrynalyne's new Battery Saver kernel.

I am using the 9/19 version. With adrenylynes kernel the built in wifi does not work.....the pre9 does work. I just tried this kernel to see if it worked or not.....it does not allow adb wireless to work, so I went back to Koush's stock kernel. I have not had any problems running the stock kernel and my battery life is quite good.

Haha thats the post I found, but I didn't read deep enough. The first post says that it uses the screen INSTEAD of the LEDs. a later post points this out as false. i wish the op had been edited

Gallery lets me set as wallpaper on 9/20... but some dark ones (black wood) look like they're all black.
Does anyone know when 6.1 will be released? I can't wait to be able to hold the back button and close the app.
I can confirm that wifi-tether (packaged and pre-9) both function as expected. No reboots overnight. Uptime of 21 hours, wifi and bluetooth on and off, mostly the former. Installing 9/20, no wipe.
i was running the 9/15 nightly for a few days with minimum apps to test stability. still had the "temp drop" problem on both incoming and outgoing calls. battery life was abysmal (8-10 hours max, light usage...something was keeping my cell standby in the same percentage as display usage and chewing up battery).
last night i got several freezes, reboots, and two battery pulls. so now i'm on 9/20 nightly. so far so good for stability, but already down 20% 2 hours after unplugging. something isn't letting my phone sleep; any idea what it might be, or how to find out? i'm running relatively few apps at the moment, but see no performance differences to when i had a ****-ton of apps/widgets running.
edit: emmc still doesn't mount in windows. shows up as 660 MB according to the OS's "SD Card and phone storage", but all the Gee Bee's are being reported as 6.6 GB under astro.

Are you using the most recent Trillian beta? If so, set it to battery saver mode or it will drain the crap out of your battery. The polling frequency on the regular mode is too frequent.

This.
Started with 6.0.2, upgraded to 9/20 nightly with no wipe. I've previously tried KK, CM6's stock kernel, and adrynalyne's AOSP kernel. Of the four, this newest undervolted kernel is performing like an absolute champ. Tethering (both built-in and pre9) is working, and I am having none of the CDMA signal attenuation issues while also using the WiFi radio that I previously had.
Somebody is getting laid for this.

Battery issue with Stock ICS/CM9 ?

So I've been testing CM9 for quite a while now and can't help notice the battery life has been reduced heavily compared to Honeycomb 3.x.
Now, I don't mind that my battery life gets a bit shorter as ICS brings more features and might be more power hungry. But I went from my tab being able to hold a charge in standby mode in 3 weeks to barely 3 days. And if I use it more heavily, it barely holds a day, which is worse than my Motorola Atrix and that's just not normal.
Now, I've been discussing this with pershoot and for him it must coming from something I do. Honestly I don't see what. In the Honeycomb days, I used to have so many apps installed (may 100-150) and battery life was fine. In CM9, I'm running 50 apps, the essential ones. All the apps that could be power hungry have those settings set to off. No push notifications, very large updates intervals (a day) or none when possible. Also, I run most on these apps on my Atrix (which has more apps installed) and my battery life is way better on the Atrix.
In usage itself, I don't see any change, it seems the tab consumes the same amount of battery than before. It's the sleeping battery life that is terrible. In my case, in sleep mode, wifi is off, brightness is set to Auto and data is off (not the signal itself but I tried to take off the SIM and the battery life is the same).
Honestly, not having to care about charging every day is a must feature for a tablet.
I'm running now RS125 ICS, based on stock and the issue is also there. So I wouldn't say it's something related to CM9 but more on how ICS behaves with our tab.
I've read report of other people complaining (with the 10.1 also) so I wonder if it's a general issue. Could you please fill the poll so we can see if there's an issue and if so, how could we identify it ?
Don't hesitate to describe your tab usage and battery life !
Thanks !
For me worsts battery life was with the official 3.0.1. 3.1 was big improvement. 3.2 and 4.x were a little bit better than 3.1.
Got gmail and exchange push notifications turned on, but most of the time the tab is connected to the wi-fi, not to the 3G network
Attached is my personal stand-by record on the 10.1v. I think it was with one of the first pershoot's CM9 roms
Hi Danny,
Same for me. Especially the standby mode I see a battery drain.
By the way, somehow my battery usage is not working since I moved to the official ICS ...
Cheers
No problem @all. Stock 4.0.4 with OC kernel.. Looks like this:

4.2.2 kernel for improving battery life?

Hello folks,
I got a SGS with carbon custom rom. It is running Android 4.2.2 . My battery life is pretty bad, i lose like 30% over night. I already reduced screen brightness but mobile standby still eats a lot of battery.
Would a new kernel solve my issue? Can someone recommend one, please?
Thank you.

It's not kernel. Install gsam Battery Monitor and check which apps are draining your battery. And check your wakelocks .
Try to greenify apps like viber, facebook etc
As you are also using 4.2.2 it has battery drain fast bug.

I use Semaphore on CM 10.2 (Android 4.3.1) but it is available for 4.2.2 and there are spme option for explame, deep sleep, maxbe it can help you ...

4.2.2 based ROMs have in general very high battery consumption. On the i9000 4.2.2 gives the very shortest battery life.
CM10.2 works much better, provides around 50% longer battery life and is faster
Thanks for your answers. I checked battery usage and wakelocks but there are no abnormalities. The highest amount of wake lock is caused by exchange but it doesn't seem to be the culprit of my battery problem. The device is awake only 9% of the time.
I found that mobile data causes the drain. When turning it on and tethering the connection I lose half my battery within 20 minutes. The battery usage is about the same when only using mobile data, without the tether.
I have installed semaphore, it gives me excellent standby times when not using mobile data...(2% over night)
2 questions: would flashing a new modem/radio solve my problem?
Is 4.3 suitable for daily usage? My current ROM is very stable and I wouldn't want to upgrade to 4.3 if it doesn't work well.
Also, I need tethering, does that work on cm10.2?
Thank you
UPDATE: I flashed Android 4.3, semaphore kernel and a new modem. I will observe the battery consumption over the next few days.

Too Much overnight Drain

Guys i am experiencing A high amount of overnight battery drain.Almost 15% battery gets depleted every night.
I am on OOS beta 10 with Ex Kernel... Android OS always consumes 13-15% battery..
Can anyone provide a solution ?
It might be one of your apps that keeps waking the device overnight. Get a Wakelock detector, look for the app that might be the cause, uninstall it and see if it helps.
It might also be the kernel I'm not sure why but EX was draining a lot of battery for me as well, but it seems to be working just fine for others. So you might also want to switch to stock kernel for a bit and see how it goes
Also, a bit unrelated, but putting your phone on Airplane Mode while you're asleep can help also. (IF you don't get any important messages or calls overnight that is) I lose no more than 1-2% over 8 hours on Airplane Mode. Plus, it's good for your health as well.

I'm not quite sure about that. I only used EX once. Once you're certain that EX is whats causing the drain, you can go ahead and ask in the EX Thread. Hopefully someone will be able to point it out. And if you're not certain, I'd say flash stock back and get only the apps you really need and see if it still drains.
And if you're in to custom business, I'd suggest you try out Paranoid Android once as well, the new build is pretty solid and i'm getting a considerably better battery life than i did on OOS, both active and idle
I'm losing 1% per hour, it seems normal for this device.
I've tried factory reset and various kernels.
SultanXDA CM13 is giving the least idle drain with this device. Rolled back to M for now, until i get best battery performance N ROM on this device.

Battery drain is too high - what rom/kernel should I use?

I've been running Nitrogen Oreo for months with Elemental Kernel, I am also on Project Fi. Recently I've noticed my phone wont go into deep sleep and EX reports idle battery drain is ~8% / hour which is way too high.
I don't run any mods etc. My battery health is also good. Should I try another rom/kernel and if so which one. I was thinking of the new Pie roms but I don't think they are fully stable yet esp for things like wifi calling which I depend on.
Usually, it's an app or some special rom setting keeping the phone awake. If you can find out what, it's usually simple to fix.
Sometimes, the stats in settings->battery will tell you what is using the power. Or try app betterbatterystats.
If you can't locate the problem, then an app like greenify may help by forcing the badly behaving app to sleep. Or clean flash without restoring all your current apps.
And yes, stay away from pie if you need WiFi calling.
