[Q] Battery Life - Acer Iconia Tab A100

Hola
I looked around and didn't see any threads dedicated to this, so I hope it's not a duplicate.
After rooting and doing the ad-hoc wifi patch, the battery life is one of my few remaining complaints about the a100
Some of the reviews that I've read (for other devices that have received a stock ICS update) have mentioned noticeably improved battery life. I was wondering if anybody who's tried out any of the leaked updates has noticed an improvement and if so, you wouldn't mind sharing some stats to give the rest of us an idea of what to expect.

I noticed an improvement in battery life by quite a bit, after upgrading to ICS, but as with a lot of things battery life is subjective. Spend all day gaming and your battery life will take a massive hammering. I don't game a lot on mine but I use it like a laptop and I guess I get a decent day out of it with full brightness and a fair bit of YouTube
There's so,e tweaks to the build.prop on ICS that add some helpings to the battery life, also if you're rooted you can use setCPU etc to lower the screen off CPU freq thus saving battery there

I haven't really noticed any huge difference in battery life when it comes to heavy usage. I get around 4 - 4.5 hours of gaming at medium low brightness. I think with the custom build prop I get more standby time and more battery life for light usage on wifi, however, I find the best way to get the most out of my battery is use airplane mode for gaming and readding.

I noticed battery management changes in general. It seems more efficient at conservation. It also shows you what apps are consuming your battery in settings now.

Thanks for the feedback. Now that I've read that the devs are working on a CM9 release, I'm totally willing to wait to see what goodness they have in store for us!

[Q] Battery Life - Stock vs Custom ROM

I'd like to hear some experiences that everyone is having on how the battery life is on the stock ROM (POST OTA, NOT OVERCLOCKED) vs custom ROMs (Again, NOT overclocked).
I've tried the Virtuous ROM, and as expected the battery life got slurped down like coca-cola! CM6.1 isn't as bad, but still seems to suck the life out of the battery quite a bit faster than stock.
Is everyone seeing similar? What makes the stock ROM so much better on the battery?
My experience was actually quite the opposite. When I switched to CM, my battery life improved by about 20-25%. I have a NAM Desire Z so it was running HTC Sense over Froyo.
Remember that it takes a few days of usage for your battery to 'calibrate' itself to the new ROM. My first two days on CM were really bad, but since then, battery life has improved greatly. Yesterday, after moderate use and 15 hours, I still had 45% of my battery left. With my stock ROM, I would be lucky to get 15 hours of use out of the phone period.
As far as overclocking goes, I haven't seen much of a difference in battery life. Reason is, even though you are overclocked when the screen is on, you can adjust settings to under-clock at other times, saving battery power.
I would recommend trying a Custom ROM for 4-5 days, that will give you a better idea about its battery life. Also, there are lots of settings you can tweak that affect battery life greatly. Widgets, background data, signal strength... SOO many variables in personal usage that battery life is going to fluctuate user to user regardless.

[Q] Any way to Increase battery life?

I'm just wondering if there's any known methods to increase the battery life without sacrificing performance. I know the basic stuff like turning off Gps, Wifi, Data, etc. when not needed but is there anything else I can do to prolong the battery life? I'm currently running the wanam lite rom with trininty's alpha 7b kernel. A couple of people reported great battery life with this combo but I'm only getting a little bit better than stock battery life.
What exactly is a little bit better than stock? How many hours are you getting?

Well with moderate use ( 3-4 hours of web browsing, playing games, etc.) on stock I get about 9 hours and with this rom and kernel I get roughly 9 and half.

I get the same too, kind of hate it :/ I don't understand what drain so much when the phone is not in use, I always wonder why stand by time is so bad in my phone, I get much better battery life rooted but I'm stock right now, I got tired of flashing roms and I hate to wipe every time I flashed so I prefer stock to stop doing that

Yeah, The rom is based off of stock H2 and is supposed to have some battery tweaks to make it last longer. All of the people said battery was good using this combo and 1 person said it's been 1 day 16 minutes, and they had 26% left but they didn't post the usage.
Ok this is with the stock rom. Heavy usage by my means any way. It was on the charger for a few mins here and there. But really not enough to show real battery increase.

The best way to determine battery life (not I played a game for a little, surfed the web over 4G, called some, texted all day) is to take a screenshot of your Screen On time, and overall time since charging. Otherwise, your statements are pointless.
If u have a rooted device u should try the highonandriod Rom it dies have better battery life than stock

Well the purpose of this thread wasn't to solve an issue with my battery life or determine my exact amount battery life, but rather to find out if there are any tricks to improve battery life. So there's no reason for me to post any screens of my battery stats because it's irrelevant to the thread, I was just wondering if anyone knew any tricks or tips they use to improve their battery life.

I'm very happy with Wanam Lite for now, it's so far the smoothest stock rom I've flashed and I'm eagerly awaiting the next update, so I don't really plan on flashing anything else for now. Thanks for the suggestion though, I'll definitely give it a shot when I'm looking for another rom to flash.
Disable auto synchronize. Thats the key.

Don't use the phone. The screen will almost always be your biggest power draw. Screen-on time is relevant because if you have the screen on for three or four hours you aren't going to see battery life that is any better.

Your right, it is relevant when comparing, but I'm not comparing anything here just looking for tips and tricks. I looked at battery stats when I compared the stock battery to the rom battery and recorded both stats on heavy use. If you want statistics, I got 9h 38m of battery use, internet and netflix took up 31% battery consumption, games took up 23%, phone calls and texting took up 12%, and the other 34% is basically screen off time. These were the stats from when I tested it on the Wanam Lite rom. I'm not confused as to why it only lasts about 9 and a half, hours as you can see I was constantly on the phone when I was testing it.

Well not only were you watching a video (I assume, instead of just browsing) Netflix, you were streaming. That probably did a number on your battery. I know I cannot stream Netflix for very long if I want my phone to last through the day. Also games, things that will ramp up the processor, etc while using the screen will tax your battery more than usual.

Some may not like my answer because it removes some bells and whistles, but I suggest turning off all the motion features. Just my two cents. Battery life was better and I found most of the motion features unnecessary.

Yeah, this isn't my everyday use, nor would I do this if I was trying to maximize my battery life. This was purely for testing the battery life on heavy usage and I found that it was only a little bit better when compared to stock. I'm in no way complaining, I think Wanam has done a amazing job with the rom. The stability is great, speed is comparable to JB roms, and battery is a lot better. Unless used heavily as shown above, then it's only slightly better then stock which is kind of odd but makes sense. I was just wondering what all a person could do to maximize their battery life, that's all.

No worries! If you have trouble with idle battery drain, something like Juice Defender will help a lot if you're going to have the phone idle for extended periods of time. Other than that, all I can think of is underclocking (I run at 1350), and sometimes overclocking your min-CPU speed can help as well. The thought behind this is is that the CPU will be able to finish tasks faster, even if slightly, and then be able to go back into deep sleep. I know a lot of people on the Galaxy Nexus forums run 700min, 1000max because of this.

Thanks, I actually didn't know that, I also heard undervolting can increase battery life and reduce the battery/phone heating up but someone said that it can it will have a major effect on the CPU, not sure if it's true or not.

[Q] Battery life

Hello.
I was wondering if my battery life is low or not, so I want to know what your battery life is guyz.
My battery would last like 12hs with wifi always on and facebook, some music here and then and youtube. is it a normal consumption ?
There are so many variables that come into play with battery life that is nearly impossible to quantify what sort of battery life someone should be getting. Screen on time, brightness settings, radios used, reception, usage patterns, apps running in the background....tons of things that will be different from person to person. Also, the actual battery itself comes into play with how well it can hold a charge.
As long as you are happy with your battery situation, all is well. If not, perhaps look into what is using your battery. Better Battery Stats can potentially help you narrow down where things on the software end are draining your battery.

That's about what I use to get.
I went out and bought a spare battery. I'm not a fan of extended batteries so I went with a standard battery for about $10.
I also flashed a new kernel that will help on the screen brightness and underclocking.

[Q] Cyanogenmod or Android Revolution 6 in terms of battery life

What would be the best ROM for battery life? I'm using CyanogenMod atm and the battery life is decent. If I flash Android Rev. would I sacrifice battery life and if so by how much?

Battery usage is completely subjective so what will be awesome for one may be absolute crap to another. Only way you'll know is to try it yourself

As mentioned, battery life is completely up to your usage. Some steps to try though which can be used across any rom is to give Rom Cleaner a shot and to use Greenify. This will rid any rom of bloat that could be sucking up battery and better allow the device to enter deep sleep where the real battery savings are had.
A well optimized kernel would give you some savings as well. I can personally say that on ARHD 5.5 with Elemental kernel .15 I'm seeing about 70% battery left at the end of a normal day. For me though that may only be one 20 minute call and an hour of screen on time. Even when flashing and messing with tons of settings for hours, the phone has never reached a critical battery level for me. I
It's more about the way you optimize (or debloat) your phone , than the ROM you are running. Use battery monitors like GSam or Battery Drain Analyzer and freeze apps that are causing you huge drain. Greenify is also good. Ideally on the M8 you can expect around 6 hours of screen time if you're optimized correctly.

This. I am able to get about 6 hours on stock, ARHD and Insertcoin. With power saver on, that ends up around 7-8 hours of screen time. Coming from a Nexus 5 that got 4 hours typically, I'm pretty satisfied. I'm inclined to believe ARHD will get "slightly" better battery life than CM since it is based off the stock ROM on the M8.
Generally the OEM skinned roms have better battery life and benchmark scores opposed to aosp. Happens all the time on Sammy phones and HTC apparently too. Posts above mine cover most you'll need to know. Its all about optimization and frankly that part is extremely fun and especially rewarding IMO. Gives me an idea for something like a community made thread on different battery tweaks/voltages :good:

I'm currently using Android Rev. 6.1 odexed (using ART atm) with ElementalX 0.10. I don't know if this is a placebo effect or not, but after flashing ElementalX(with default settings) my battery life seems worse :/

General RAM boost, Much better battery

Hi folks
Since I disabled the RAM boost option, my battery feels so much better!
Version 11.2.8.8 Indian
Im with 75% screen brightning
QHD + 120Hz
Wifi - ON
4G - ON
Bluetooth - ON (Connected to device for 1 hour)
And my SOT is 4 Hour, 9 Min on 50% battery now.
7 Hours since last charged.
Finally some better battery life ...
Hope ONEPLUS will fix this problem. So we dont have to tweak settings for better battery life
I don't think it needs a fix. It's simply utilizing more RAM to prioritize and that alone will speed up battery drain. The OP9 Pro is meant for speed. Performance vs battery life is a constant battle. Try 50 percent brightness when your inside. Also do you have developers mode enabled
Developer enabled, yes, why?
You can make a few other tweaks to increase battery life. The four scale buttons you see can be brought down to .5 as well to save

Of course. Everything impacts the battery. The question is how much do you want to lower your viewing experience to save battery? That question can only be answered by the user.

That's going to make such a negligible impact on battery life lol. If you think that's helping a noticeable amount, you're kidding yourself
I never said it would make a huge impact. I'm just adding things in that people do to Maximize battery life. I personally do not throttle my performance. I enjoy it how it is and to fully charge takes less than 30 minutes
Wish I could say the same. RAM boost on or off I still average six hours of SOT
Every little thing can add up to a better battery experience...
Animation OFF will give you some plus in speed too. I keep them off for years. It's usselles for me.
