Deep Sleep to Save Battery - Acer Iconia Tab A100

So I want to love my A100, but one thing always brings me back to my iPad. It's always dead when I pick it up after a while, whereas the iPad seems to really save battery when not in use.
Is there a setting I am missing? Is there a way to get it to not drain like this?

[Q] Battery life

How's the battery life on this phone? I'm thinking about getting it.
Battery life is *ok*.... But for me, i can unplug my phone at 7am i the morning, and by 10pm when i go to bed, im typically around 15%-30%.
To do it, i use a task killer (i prefer the one by rhythm software). I keep things closed that dont need to be running. Also, i dont use the stock launcher, i believe that launcher is part of the problem since once i switched from it my battery life increased quite a bit! I use Launcher Pro.
Turn off your location settings (wireless networks and gps). Keep your screen timeout low, like 1 minute, and get yourself into the habit of pressing the power button to shut off your screen when your done.. Prevents butt-calls and saves battery!
A lot of people say the battery sucks, and keeping everything stock-ish, yes it sucks.. But when you customize the phone to your own feel with a few small tweaks, its better than most phones!

How long is your screen on, on average?
I just bought the qcell 3850mah extended battery and I have to say it was worth the $20

Very hard to say! But i send around 5000 text messages a month, probably spend at least an hour a day on the internet, checking emails, etc... Maybe another hour doing other random stuff? Lots of text messages and a couple hours with other stuff.. So not a TON, but not a little either.
at the beginning you will hate it !
a couple of recharges and drains till the phone shuts down
ofcourse root and remove all the bloatware and do battery calibration, and now... its the best battery on a smartphone i have ever owned !
lasts much longer than my second phone iphone 4S and xperia S
definitely much better than the S2
Battery's Great Now!
I've rooted, switched to Go Launcher, and running Juice Defender balanced profile. With moderate, surfing, messaging, email, and occasional tethering, I'm getting 2+ days. Manage to get a nice LTE signal from home. Dang! It's faster than my AT&T U-verse.
2+ days sounds very impressive. I must say its true the battery life gets better after some time, but for me its now about 18+ hours with not so much use. I guess it also depends what kind and how much apps you've installed and if they run in background-mode.
I've made the weird experience that sometimes for maybe 1-2 hours the battery status remains on one level, but later it drains a lot in very short time (usage is same like before). So unfortunatly not really reliable.

Forgot to mention what this guy said! Remove the bloatware! Tuns of that crap stays running in the background whether you like it or not! So if you use Titanium Backup after rooting, you will definitely have one of the best batteries on the market! I woke up and unplugged my phone at 5:30am, here it is 19 hours later and my battery is at 31%

[Q] How to super Optimized Tmo Sammy S2 for best battery performace?

So I switched from the iphone with edge to the Tmo S2 with Jugg 5.0 ROM + Go Launcher. I really appreciate the 4g speed. However, the overall experience is not as smooth as the iphone and the battery life sucks big time. I normally have to constantly plug the phone in whenever I can. It works ok when I'm at work but when I'm out all day my battery won't last more than half a day. It's so bad to the extent that I have to turn off my phone and turn on when I need to call or text so I can keep the phone alive the whole day. I tried Juice Defender but it didn't help my battery at all.
Yesterday I spent a few hours on XDA and I came up with these solution to my battery problem:
+DarkSide Digital Warfare v2.7 ROM (couldn't find 2.5.1 version)
+Flash Synergy Kernel over (supposed to give better battery)
+SetCPU app (auto detection)
+Zeam launcher
So far, it seems to be better on the battery. Is there anything else I could add to make my battery last longer? I need the phone to last at least the whole day without charge. I'm constantly on 4g looking up stocks, reading news, email, google voice, grooveip, facebook, turn by turn navigation, music, netflix, youtube ...
Thanks,
Welcome to Android.
From what it appears, you seem to be a heavy user. The most you can get out of a Android device with heavy usage is 3/4 of a day (14-18hrs) tops.
You have 2 choices, either you travel with the power cord not to far away and plug it when you need it or you invest a whooping 10$ and buy another battery.
There are tricks to keeping your battery healthy but lasting all day as a heavy user will be very difficult.
If this is a new phone it takes a week or so for the battery to settle in a hold a charge well. After a week or so you'll notice your battery is lasting longer. Also make sure that nothing is keeping your phone awake 100%. Some apps don't play nice and cause issues. Welcome to Android.
Note: navigation kills battery fast, when your using it try to plug into a car charger or something.

There are a lot of things you can do to improve battery.
1. Juice Defender (which you say you have already tried)
2. Limit the number of widgets you run or run no widgets like I do
3. Turn the screen brightness down all the way
4. Don't use Live Wallpaper, also, try to pick a dark coloured wallpaper since white/light colours seem to use up more battery.
5. Uninstall apps you don't use.
6. Turn off GPS unless you need to use it.
7. Turn off sync completely or only have your gmail sync. I don't need to be notified when I get a facebook message so I don't need it syncing every few minutes or every hour, I can check that manually myself.
8. Turn off animations.
9. Close background apps that are running that you aren't using.
10. Use Task Manager to close open apps when you are done using it. Task Manger is your friend.
11. Enable Power Saver Mode.
etc etc.
Those are the main things that I tend to do. I plug my phone in every night before I go to bed as well so I am not sure how long my battery actually lasts. But typically after 16hrs of use I still have 60% battery when I go to bed.
Currently my phone has been on for 7hrs 15mins and I have 87% battery. So you can do the math. I am not as heavy a user as you seem to be, but hope this helps. Peace.
Check out this video it helps show you how to save battery. Enjoy!
Thanks for the inputs guys. I should have said I was looking for Rom/Mod/Scripts/Apps... that can be flashed onto the rooted phone. I have done all the basic battery saving housekeepings as listed by Chochiwpg.

I'm up 5hr 45mins on battery and my battery is at 41%. Let's see if it will last for today. I will put Juice Defender in tonight to test out the battery tomorrow.

You could run Juggernaut with Faux Kernel and Gideon's battery scripts. Or Telus T989D stock ROM lightly tweaked with same kernel and script. Got good results on those as well. Good luck.
Btw, has anyone had tremendous increase in battery life using the after market extended battery?
Thanks,
Use fox star rom

If you are talking about extended batteries that don't require a custom enlarged back cover, you will not get the battery increase that you are looking for, not even close. I cannot speak for the heavy duty ones that require an enlarged back as I do not own one
Gideon's scripts are great with Juggs. Underclock it as well like 384-1080 is a great setting. Also let die all the way down and charge all the way up and repeat for a few cycles. And don't stare at your phone every few seconds either lol! Another thing are the notification lighting buttons at the bottom. Drop to 1.5 seconds.

I have the extended 3800mah battery. It's insanely fat and makes the phone look hideous. On top of that I really don't feel like the battery lasts all that long at all. It's in my pocket all day at school and by 3:30 I'm at 35%. This thing cost me 65$. Total ripoff. I'd suggest spending 20$ and buying two more regular batteries. See what that does for you all

A few things you can do on ANY ROM to improve battery life.
*) Decrease screen timeout to the lowest possible setting.
*) Adjust screen brightness to the lowest level you can tolerate.
*) Decrease the backlight key timeout to the lowest setting ( or off if you have the option )
*) Be sure to only have wifi and gps on if you are using them.
Those will help quite a bit in general however, a ROM like Juggs is meant to really take advantage of the power of your device so its probably wise to move to a different one if max battery is your goal. I love Juggs but had to move on to the AOSP stuff. Also, heed the advice above, allow the ROM a few days to "settle" before making a switch or even a judgement of its performance.
Thanks for the replies guys. So my phone lasted for 9hrs today which is a little bit of improvement. I was streaming netflix for half an hr on the train on the way back home so that may have drained the battery. I have just installed JD, will post back how it goes tomorrow.
So the extended battery is a no go eh. I really don't want to lug around a few extra batteries. I want to carry as little as possible. I normally carry my phone and my ipad but now I tend to not use the ipad much now because the S2 screen is pretty gigantic for a phone.

I know the point was already made but just to reiterate, you can get 2 Anker extended batteries (same size as regular battery) and a universal charger for like $20. This will leave you with three batteries. One for the charger, one for the pocket, and one for the phone. With this system its pretty easy to always have one full battery ready to go and one charging. The battery is small and can just go in your pocket, or maybe even in your wallet depending on your preferences. It solves the problem completely. I don't think you are going to do much better because if you are a heavy user then your battery is going to be used because your phone isn't going to be sleeping.
Good luck.

If you read my post above. I'm against the idea lugging around too many things. It's also a hassle to swap the battery and keep them all charged. I may be a heavy user but it's not like I use the phone all the time. I use the phone heavily early in the morning on the way to work and after 5pm on the way home after work. The commute each way is roughly 45 mins. In between the commutes i make a few calls and texts through GV. I don't think i'm that of a really heavy user.
Anyway, it's noon and I'm at 75% with JD on and setCPU to 384-1084mhz which is pretty promising.
Questions go in the Q&A section
Since you changed kernals, you aren't going to benefit from TDJ's battsaver script you can use with the stock 2.7 kernal.
Go lower on the max frequency. Something below 800 mhz. Setting a negative gloval mV doesn't hurt, and if you can get to -62.5, that's great.
Oh, and when using data, try GSM only...
To be honest, the larger problem with battery life is typically the user. There's no real magic on making the phone last longer other than using it less. If you're going to be power using the hell out of it by using 4g for hours streaming media, your battery is going to be ****.

Don't you think it is ironic for me to switch from the iphone to the S2 because I couldn't stand the slow 2g Edge connection then have to lower data speed to GSM (2g) just so I can use the S2 long enough?
I think the S2 is one heck of a device but the OS and Apps are not running very efficiently.
I tried the ICS ROM ARKSIDE.UCLE2:: x[BETA07.1] in the last 2 days with setCPU at 384-1026Mhz. I have had great battery life. I got home at 12 am yesterday with a 2% battery. Today it's been 7 hrs on battery and my battery is at 70%. I don't know if it is the ROM, setCPU or a combination of the two but I'm pretty happy with the phone right now. ICS is awesome too.
I highly recommend that solution to anyone having a short battery life problem with their S2.
It is a little ironic since you did bring up the comparison. What I was attempting to do was to bring the phone more into spec of an iphone to get similar battery life. You're probably going to even get better runtimes due to the battery having a much larger capacity and better screen technology. All that superior hardware packed in the t989 is going to need more juice to run.
It's great you're getting good runtimes now. From my personal experience, once I drop down to the single digit percentages, it starts lasting a lot longer per percent. If you wanted to squeeze all you can from the device, those 2000mah aftermarket cells might add another 15~30 minutes.

Standby Battery Life?

I know there are threads regarding battery life out there, but most are all about usage and screen on time. My Note seems to be on par or at least close as far as screen on time. However, I'm just curious as to what all of you are experiencing as far as standby time. I've gone through the battery life guide and turned off most features I don't use, but the standby time still seems pretty lame. From a full charge, its been 3d 5h on battery with zero screen on time other than checking the battery stats right now, and it's down to 9%. Android OS consumed 57% and Google Play Services 33%.
I know I'm comparing Apple and Oranges here, but my 4th gen iPad I have for work hardly drains at all without use. After a week of standby, the iPad will only drop about 5-10%. I feel like this tablet should be capable of the same, and possibly will be after I root and find a good rom (also don't like to see any Apple product out-perform any android based product). Am I alone here?
Basic setup: Stock Rom (not rooted), Nova Launcher (prime), GPS off, Bluetooth off, reading mode off, multi-window off, screen mirroring off, s pen detection off, all samsung crap off (air view, etc), and others. Basically the only thing on is wifi.
I only have wifi off during standby and it drops 1-2% every 12 hours
You might have a tough time getting people to compare their standby time with yours... most people on this forum either use their tablet for work and if not are too in love with their baby to let it sit there untouched for days on end When I couldn't use mine for 12 hours, it dropped about 3% with WiFi and GPS on
Sent from my SM-P605 using Tapatalk
Yeah it is too hard to not touch it for days on end to test this. Turning off wifi while in sleep mode will help a lot. Go to the Connections tab in settings and hit the hardware menu key, then choose Advanced, and change Keep wifi on during sleep to never. That has helped me a ton. Right now mine is at 2d 7h 40m uptime with 4h screen time and it's at 32%. Even with that setting on, my iPad mini still gets better battery life. I have left it sitting for 2 days before without touching it and found it sitting at 92% battery life with wifi always on. My guess is it's something to do with the OS and iOS is just more efficient. That's why even with weaker hardware it can still outperform android tablets.
Also I'm still running a lot of the things you have turned off. You might want to also try Greenify. It has a non root working mode now, but works best in root. You can also try Wakelock Detector to see what apps are waking your cpu, so you can see what to Greenify. If you root you can also try an app to freeze apps as well like Titanium Backup and Rom Toolbox.
yeah, forgot about greenify. you have to be rooted though an need either the donation version to greenify play services(that's the battery killer) or use titanium to make it a user app to greenify with the free version. it's sad that google is the worst culprit with battery drain on all my devices.
I get 1-2% battery drop every 24hrs of standby. WiFi must be off, it not hard to just pull notification bar down and touch the wifi section off whenever you think you wont use the tablet for a while - takes like 2 seconds.

I have yet to try my battery life with wifi off, so I think that'll be next. I really don't need it connected while the screen is off, so I'll change that setting first.
I figured it might be difficult to get a good response for this question because I too have a hard time putting the thing down. Was just traveling for work and had it in my bag those 3 and noticed the battery drop. I appreciate all the suggestions and welcome any future ones. In the mean time, I'll be experimenting as well and report back if I find anything causing the drop.

Do you leave always on display/clock on?

Do you guys leave always on display on? Should i leave it off the save battery?
I turned mine off. Kinda pointless IMO.
I don't think it is a substantial hit. It turns off when in a pocket.
Sent from my SM-N930T using Tapatalk
Only you can decide what amount of screen on time you want and what gets sacrifices to get there. I'm easily getting through the day without turning it off and I like having the information. If you like it and you're getting the battery life you want by all means leave it running. Shiny new toys would just be new toys without the shiny.
I have it on from 6am to 10pm then off while I sleep. I find it useful at times during the day.

I have it on, not a great batt drain, it loolks awesome, thknk about this, You want a great device, full of functions, real unique charateristics, , so? why all rhe compñaints about battery life? if so concened boit batt life, go get a chimese unbranded set
I turned mine off the day I got it. Reason for that since it uses AMOLED screen which means over time you'll get burn in (actually it's really burn out) which can't be fixed. From what I understand it moves slightly to prevent that. Still why chance it?
I have mine on all the time, but honestly I find it can be distracting often. I have gotten to the point of NOT wanting my phone to be bothering me 24/7, and have found actually turning it off for days at a time is a good thing. But that's kind of a different point... fact is, the AOD is something that attracts the eye and attention, and I find myself turning my phone face down or away from me so that I am not constantly looking at the AOD. Not the phone's or AOD fault, just how this works. It is nice to have the option of AOD and I don't think it effects the battery life much.
Mine is only off at night because I like to sleep in the dark. All day long it's super handy to be able to glance down at the phone to see the time and other info, plus it looks cool.
I keep it on 24/7. The battery consumption is too minimal for me to loose the information it provides if I were to disable it. As long as my device can last two days on a single charge I'm happy.
under what I would class reasonable use I'm getting from 6am till midnight and still having 40%+ of battery so can't really complain as it's not running the battery down enough to the point where I would want to save battery.
Love this feature and never turn it off. Makes a great night clock.

[A520F] Battery problems

Hi guys!
I have a serious problem with a used A5 (2017) I got from some friends. The battery life is abysmal. I already changed the battery and it didn't change anything.
It is running on Android 8 Oreo. The most serious problem, I think, is that the phone even discharges when it's powered off. I tried using the latest hadesrom, but it didn't changed a thing. Lifetime is around 12hours, doesn't matter if I run some apps or just let it lie around in standby. I tried factory rests and some battery saving apps... nothing works. Is there any way to get better battery life? Thanks in advance!

You could try the naptime app. But I don't think my battery life is any better than yours.
The a5 2017 has a famously good battery life.
I am not a heavy user - make and get few calls and mainly use it for receiving emails and a few texts plus a bit of web browsing.
Occasionally listening to podcasts.
3 days battery life is easy for me - reckon I could get 5 days if I just left it sitting quietly.
If it's going flat quickly even when switched off, it sounds like a fault somewhere.
Don't know what else to tell you.

I never tried letting it sit, but if I just left mine alone it would last for days too. But if I am gaming on it, it will go down to around 50 percent at noon.
wow - 3 days life battery!! I can hardly get to 2 days, without heavy us - but I would never try to change the battery -> sounds too complicated
One thing that is worth looking at is the Always on Display (AOD).
I found it sucks a lot of power despite the claims that it 'doesnt use much'. It seemed to use around 1% an hour - I guess thats around a quarter of your battery in a day. So unless you find it useful either turn it off - or set it on a schedule for when you actually want it to be on.
Battery life is always sujective and depends on what your phone is doing - gaming will burn through a battery like nothing else.
The OP said the battery drains even when the phone is switched off - That sounds like a hardware fault. The battery will gradually drop when switched off - but it should take months for a healthy battery to drop much if the phone is switched off.
