my battery drains like a bugatti veyron doing 252mph constantly
so what would you advise . is the kernal i have now the best or should i change .. i dont want to reall lose much performance on what i have now but would like the battery to maybe improve if possible ...
from full charge taking plug out searching market for 2 mins the battery drains 5-8% in matter of mins
and i have only had the phone a week
With that kind of drains the problems the kernel won't change that much. There is probably a app that causes the battery drain so looking in to that will have more effect. Also the brightness/screen on is the biggest drain and kernel won't do much about that.
You said that you have the phone a week, the battery needs some time to reach it's full potential and you probably use the phone a lot because it's new. So use the phone normally for another week, after that week let the phone drain until it shuts itself off, leaf it off and charge it till it's full. (there is a different calibration method but this always worked for me)
What do you have now? Stock or rooted?

First of all, I would assume that you don't use the phone non-stop (it would be justified to lose power in a few hours if you're on it non-stop).
I recently had issues with power consumption as well. What I did was:
1) check the built in battery monitor: menu-settings-about phone-battery-battery use. The bad thing about this monitor is that it does not differentiate well the apps consuming power, but you can still see if there's something wrong, as the most consumption should come normally from the screen and voice calls. For me, the most consumption was made by com.htc.bg, which, if I let the monitor on for a few seconds, would transform in the calendar app. Weird stuff. I unchecked the calednar auto sync from menu-settings-accounts and sync. It may have slowed the power loss down, but not significantly. I noticed a significant loss of battery by WiFi. I realized, I needed more information so:
2) I installed an app called 'Power Tutor'. What it does is, it calculates which apps consumes power, and it shows you in percentages. After install, you need to start the 'power profiler'. It will appear in your notification bar. If you let it run, after a few hours, you can see in "view application power usage" who is using power. That's how I discovered that my winamp app was really off the charts using power like crazy. So I went in the winamp settings, and I unchecked some options that could have determined this power consumption, like wireless sync, automatic mount as USB drive, etc. There was actually an option that was overriding the wifi power management, stating that the wifi does not stop after 180 seconds of standby. Basically, if you have wifi on, and you stop using the phone for 3 minutes, the phone automatically turns off the wifi. This was not happening any more, due to winamp. So I unchecked all those options, and voila. It worked, I have now normal battery life.
Good luck!
be aware of a couple of things
1. battery drain for the 1st few weeks are high because of a couple of factors, the battery "learns" and gets conditioned over a period of time (doesnt use the old 16hr charge process). its a new device for you so its a novelty, you probably mess about with it with the screen on more than you think.
2. there is a configuration within HTC's builds and in the memory chip of the battery to stop over charging. the device will charge to 100 and then slowly deplete to 90% while still saying full on the phone. as soon as you disconnect it recalibrates to the correct value which is anywhere between 90% and 100% depending at which part of the cycle you catch it
Some other tips to increase battery life, from a friend of mine in the Romanian forum:
1) use the app watchdog, it will warn you when an app is using too much of the processor and will ask you if you want to close it.
2) juice defender with the paid add-on 'ultimate juice' - with the correct settings... it's amazing.
3) Dial *#*#4636#*#* - phone information-network type: select gsm auto prl. The phone will stay on 3G when it has good signal, and switch to 2G when it doesnt, saving battery
4) Change the wallpaper to a static one, not a live one.
5) Go to menu-settings-accounts and sync and increase sync intervals for weather, news, or even set them to sync manually when you choose.
i will try and answer everything at once ..
ok my screen is on 13% brightness
i hardly ever use my phone , the only real use was to root , s-off, put ROM ETC ON
I reply to about 50 texts ish per day and search the market for literally 1-2 mins to see what new apps are in
i dont play games or anything
the thing the battery uses most is the screen and as i say i have it on monochrome theme with 13% brightness, there is nothing synced , i check automatically for email etc .. actually beautiful widgets is set to auto update every 4 hours
i never use wifi as i have a 3gb download/data usage, i dont use gps ...well i do but i have had no need to .. thats about all i can tell ya
rastaman the pt2 is a bit weird it should stay at 100 if just taken out of charge
I calibrated the battery and that made no difference.

So I think by now everyone has realized the battery life on our A100's is mediocre. I've actually been pretty content with the usage I get out of mine. What I'm not so thrilled about though is the idle usage. I'll leave for work in the morning with my A100 at / above 90% battery and come home after 6pm with it completely dead. I have wifi set to turn off when the screen does, any app I have that has a sync option is set to 6+ hours, and I've stopped using live wallpapers. Every other electronic device I have can usually last a full day when not in use(my old netbook gets 3 hours of use on battery but 2 days while sleeping).
I've started looking into the "bloat" / OEM apps installed by Acer. Nidus, sync, socialjogger etc... My main questions are; what can be removed, what can I live without or would be better of with a 3rd party app, and which Acer apps can possibly be causing the idle/sleep battery drain? This thing should still last a full day while sleeping, shouldn't it?
Any suggestions? Anyone else have this issue? Thanks!
You could try using Bloat Freezer to freeze apps. I have alot of the acer stuff frozen, and with it in standby, easily goes a day. Things like socialjogger, acer init, etc.
These are the apps I've completely removed from system apps, made a backup of course..
AcerClockwidget.apk&odex
Agendawidget.apk&odex
Aupeo.apk
Clearfi.apk
DTG.apk
LinkToFacebook.apk&odex
MusicA.apk&odex
MyLocationWidget.apk&odex
NemoPlayer.apk
Planner.apk
SocialJogger.apk
Solitaire.apk
Xt9.apk
You can also remove appinapp butyou will loose the games multimedia app I use that so kept it.
Battery life hasn't been that bad on mine. I expected worse, I just picked mine up last week and after reading reading reviews I expected worse.

WOW! I can use mine all off and on all day and don't have a problem. There has got to be an app that you are using that is destroying your battery when idle. If I don't use my tablet all day, it will last 2 full days (with wifi kept on).
That's what I was thinking. I get a decent amount of usage from it; it's when I'm not using it is when I feel like it drains the most.
I started freezing apps last night and let it charge overnight. I've still got to go through my apps and remove a few I don't use, and check to make sure they're not syncing too often. Do you all leave your gps and wifi on all of the time or have them shut off while the tablet sleeps?

My settings are to never turn WiFi off and I always leave sync on; I like getting notifications and app updates. I have a weather app that updates every hour and Pulse news that updates every 4 hours.
I also always leave my GPS on, but there aren't many apps that use it while it is not in focus, so I rarely ever see GPS pop up on my battery usage list.
I do not use a live wallpaper.
I found that with wifi on, my tablet drains about 1.5% per hour when idle.

I suggest other than setting wifi to turn off when screen is off is to use a wifi toggle widget. You really never know what happens when the screen is off if your wifi is really turning off. Wish it was built in to the quick launch though like some Honeycomb tablet.
You can also use setcpu to setup profiles so that when the screen is off the processor stays at a slower speed rather than jumping into high gear when something wakes it up to sync. I've been able to go days without having to recharge (but I only use it for reading books, listening to the music I have on google music and play order and chaos every once in a while). I havn't touched my a100 in about 4 days and its sitting at 62% battery power.

here is my usage, I never turn off wifi no profiles
I don't necessarily think you need to remove any of the stock app. My wifi is set to turn off when screen is off, GPS off unless I need it (apps like facebook will use it when you open it since it tries to get your location for checking in even if you're not checking in). Gmail is left at default but other mail is set to never (I just manually sync it when I open it).
If you wanna go a step further, you can install a wifi on/off widget to completely turn it off just incase an app is trying to use wifi.
With my setting my battery drains about 1-1.5% an hour when screen is off. IMO the screen is what uses the most battery. However though after conditioning the battery for 3 cycles it's been lasting longer.
I was just about ready to return / exchange my a100 so I did a factory reset on it. Lost track of time and forgot to, so I just decided to boot it back up and play with it. Left it alone at around 70% yesterday afternoon, came back home at 7pm today and to my surprise it was at 40% battery remaining. Must've been an app or setting I had that was killing it.
Probably end up hanging onto this awhile longer. Great tablet for the money!

Also can freezing apps brick your tab as well? Or does it defrost itself after boot?

I think with the 1gb ram on our device there shouldnt be a need to freeze any app and it doesnt defrost itself on reboot. Atleast it shouldnt.
Also I found for the most part if an app can be deleted it will let you delete it by dragging the app icon in the upper right in the app drawer. This is probably the safest way to delete rather than doing it in root explorer or TU.
This might be a dumb question but is it possible you have wifi issue that i've had on 2 a100s which will prob cause it to use more battery as its trying to work harder locking on.
It seems for the moment my battery issue was resolved with a factory reset. I have nearly the same apps on it now as before and my a100 hasn't been dying overnight. Don't believe I've frozen anything this time around either.
I don't think ram has a whole lot to do with it. I just figured some of these apps were starting themselves or syncing often, causing the battery drain.

Do you have a lot of widgets that requires syncing like youtube, twitter, weather, facebook? Those are the apps you probably what to check. OR you can just turn off wifi if youre not surfing or streaming.
Here's mine with wifi turned off. It was at 89 but I had to turn on wifi so I can find a screen capture app in the market. I have lots of apps including facebook, twitter, weather widget, which cant sync cause the wifi is off. Have not removed any stock app. I know this doesn't really answer what you asked but I'm just thinking something else might be wrong other than apps. Maybe its your battery not holding correct charge. Have you tried calibrating the battery?
I tried calibrating the battery the first time around. This time (after the reset) I haven't done anything special and have so far been getting 2 days of idle/light use before needing a charge. Satisfied so far. I was mainly concerned that I wouldn't be able to go on a trip without it needing a charge while sitting in my bag for a day without use.

Screen Brightness
For 99% of users, the display is the #1 consumer of battery, which makes sense because you have a giant 4.65 inch 720p display that needs lots of power to run. The lower you set your brightness, the more battery you save. For a person like me, 50% brightness is usually the highest I use. Colors look clear, the screen is plenty bright to read, and yet it's not too high. If you want to save battery however, turn down the brightness to around 30%. If you're really in a pinch and need to save some juice, you can even turn it down all the way to 0%, but I would recommend keeping it around the 30-35% mark for general usage. In my experience, standard auto brightness doesn't work too well for me. It's slow to respond and either cranks the brightness way up or way down inappropriately. However, some ROMs like CM10 allow you to modify the backlight settings, which works quite well.
Maps/Latitude
This tip is a little more straightforward. If you use Google Now, you are using Maps location services which drain battery. It's always looking for your location to give you the latest weather, let you know about the cool sushi restaurant down the street, and other neat stuff. However, it needs to know where you are, so it's constantly polling the network for location data. So, shut off Google Now completely, or if you're like me and love it, just shut off the parts of it that you don't need, like Places and Traffic. I saved the big one for last. Latitude. The silent battery killer. If you're like me and you never use Latitude ever, guess what, it's probably still using your battery, so you need to shut it off. Simply open your Maps app, hit menu, then settings, then location settings, then disable location reporting and location history. Your battery drain should decrease significantly. I check this often because it seems to reenable on its own sometimes. Yikes.
Radios
WiFi is pretty fast at your house. Way better than 1 Bar of 3G. But when you leave, you leave the WiFi on, thinking it's no big deal. However, WiFi is one of the biggest battery killers, along with the other radios. So remember, just shut stuff off when you aren't using it. No navigation today? GPS goes off. Not using your headset? No bluetooth. Haven't invested in those fancy NFC tags? Shut that off, too. A big one is LTE. If you live in a 3G only area, what good is it to keep LTE on? It's just draining your battery. Turning Data off can save you money and battery. If you aren't one of the lucky ones still on an unlimited data plan, shutting data off will stop apps from using data in the background, and it'll also save a bunch of battery. However, you won't know when fnartsy123 liked your Instagram photo.
Apps
There are some apps that constantly use system resources and keep your device awake, even when you aren't using it. A major offender is Facebook. While a big update is rumored, the apps frankly sucks right now. It's slow and it drains your battery. Stick to the mobile website, as honestly, it works better now. That's the main one, but there are plenty of other. To identify them, I recommend an awesome app like Better Battery Stats or Appsucker from Google Play. They'll tell you what app is stealing your juice, and you know to remove it.
Auto Sync
One of the main reasons to own a smartphone is to stay connected, and I don't want to change that. I would recommend you shut off syncing for services and apps that you don't use. Check your Google account settings. You don't need or want all of your selfies to end up on Google+? Shut off instant upload. If you use Chrome instead of the AOSP browser, shut off sync for that. Go through and make sure you only are syncing what you actually use. Also, check your apps. Do you need to know when you have a new tweet? If so, leave it on. If not, shut it off. Furthermore, if your battery is in the red, shut off autosync altogether to save some serious juice.
Good tips, especially turning off google now, its useless and even worse its a huge battery hog.
Nice article mate. Very useful tips. Good job. :thumbup:

Great tips, but Id just like to make some additions:
Use Y5 to turn on/off wifi based on your location
Use Tasker to set a schedule to set auto-sync on for 2 minutes at 30 minute intervals.
nice guide, thanks
Just to let you know that you can keep the gps setting on. It only uses power if you are using the GPS. So yes if you have like google now checking for your location it will use power but if you don't have anything automatically using GPS then you can keep it on and it won't use battery.
Another one that I use, i if you are root, i change de voltatge settings to lower value or turn down the speed

Hello People
My phone charger recently went "kaput" on me so I've been using the built in Extreme Battery Saver mode a lot. I really like the functionality of this and was wondering if there was a way to start this mode when you put your phone to sleep no matter what your battery level.
Say for example I was at 80% battery and I put the phone to sleep is there an app or maybe a Tasker profile that is out there that would make the extreme battery saver mode start automatically ?
Thanks

To directly answer your question... I'm not sure. But that's what battery "saver" apps apparently do also.
But as long as you don't have an issue with wakelocks, there should be no reason to do this. Most will tell you that in fact, you'll likely waste more battery life you save... Just like battery "saver" apps. Reinitializing data, WiFi and whatever else you have, every time you turn on the screen will waste more battery than the small amount of drain they normally cause while in standby.
Keep location off. Google now off. Keep screen controlled manually and as dim as is comfortable. And watch for poor signal while on data. That's all you need basically to have good battery life. (that's a simple look at it anyway)
My 2 cents. :good:
Hello Guys and Gals,
Its been awhile since i have been on here. But i have been very satisfied with my Note4. However. It had come to a point that carrying 4 batteries with me to make it through the day was too much.
Here i am . Finally upgraded to the 8+ and overall. I am very dissapointed.
So. i would like some input on what changes you have done, as well as apps running, how much you use the device, your daily connections. and so on.
i have:
Bluetooth always on, connected to my Gear S2
Location services always on
I am a big social media junky, on FB, and IG, not too much of Snapchat.
I use Line to talk to my group that i game with
I play Transformers Earth Wars, about 15 minutes at a time a few times a day.
Do not use bixby
Screen display is set at Amoled Cinema, HD resolution, auto brightness is turned off stays between 30-60%
Very Rarely use WiFi
Google apps do not auto Update
USB Debugging
3 gmail accounts linked, sync is off
Anything else just ask,
So after my 8hr shift of work, my phone is at about 40%, my Note4 on would almost make the whole day, i would get to about 20%, then i would switch batteries.
I am not happy with the battery. Just seems like for no reason it is draining.
Comment below, let me know your setting, impressions, and so on.......... Maybe im doing something wrong and dont realize it.
Well your first problem is all the social media apps, pretty much all of them just destroy battery life. When your not using those apps I would put them to sleep.
You need to monitor which apps are draining the battery. You can do this through the stock device mait. app. Once you find out which apps are causing the drain we can go from there.
I use standard mode, screen on WQHD, sync always on, all data no wifi, screen at 50 % or higher. No social media apps, I use the browser for those.
Here's some screen shots of battery life, this is and average battery cycle, I have reached over 9hrs of Screen on time (SOT) and 1.5 days in previous cycles.

Believe it or not sometimes that consumes more battery life having to open the app every time vs just letting it run in the background. Probably not true with social media apps but it's worth a try. You may also want to try a package disabler app from the play store to disable apps you don't use that run in the background. I use BK package disabler.
