The Great Battery Experiment

I have two Arias, one freshly rooted with the rooted stock ROM and one running attn1's FR008 flashed straight from the freshly rooted state. The only additional app installed is BattStatt, so I can easily monitor battery state. One battery is new, with only a few cycles (over about a week) and one battery is older, purchased in August.
Over the next few nights I will be doing an experiment. Both phones will be on, same settings for GPS, WiFi, Data, and Bluetooth. They will only have the displays set on about every hour or so to check battery states. The following night, the test will be done again, with the batteries swapped. I will then run the test again with WiFi on, with intermittant connections due to my work environment.
I expect to update this thread after each night's experiment.
The first night is an exception, I'm comparing my normal ROM (loaded with apps, widgets, and running Tasker) My first night has been interesting...one running freshly rooted is still 100% after 1.5 hours. The FR008 with many apps is down to 89% (note that this is the older battery). Perhaps at the 4 hour mark, I shall swap them. It would be nice to do this with 2 new batteries, but I have what I have.
This is being done to lay rest to the claim that one ROM gives better battery life over another. Seems like it is going to be conclusive if the first night is any indication. Perhaps we'll see what app is the culprit? (Widgets??Tasker??)

Phone calls?

Interesting article regarding battery life
Interesting experiment !
Just FYI - an provocative article :
Your Battery Gauge Is Lying To You:
Everything You Need To Know About Bump Charging
And Inconsistent Battery Drain

No phone calls on either. Just to be fair, since one is without a sim card, both of them have data turned off.
At the 4 hour mark, the original rooted ROM is still at 100% and the FR008 with mucho is at 82%. I have swapped batteries.
This gave me an opportunity to race bootups. The stock ROM booted up and was usable before the FR008 (with UOT cooked startup bootup animation) even got to the dancing droid. Makes me want to undo that to see if that is slowing down the bootup.
I am eager to do this full swing with clean ROMs tomorrow. I shall make a backup of the FR008 ROM then go back to the aria_shipped_rooted_signed.zip
(found at http://forum.xda-developers.com/showthread.php?t=783508&highlight=Original+ROM). I will then flash FR008, adding only a widget for easy monitoring of battery levels, BattStatt.

This experiment is going to have to wait. Part 2 of last night's experiment indicated that my older battery drains fast in either device/ROM. The article linked in this thread is good reading. Thanks for that info.
My last Intruder was a Grumman A-6E.

Awesome idea
What a great idea - I hate the battery life on my Aria, and have tried multiple ROMs and multiple battery programs. I look forward to watching your progress with different settings and ongoing informational reports

I pretty much ran a similar test
I have two Aria phones - both the same age
one is stock 2.1
one is FR008
I set them both up the same - running HTC Sense -
I set the phones down (while I slept) for 8 hours
the stock phone drained 10%
the FR008 phone drained 43%
Did it twice
I know its not a 'real' test , but it does make you go hrmmmmmmmm.

If only you had a 3rd phone to throw CM into the mix! lol

You set the phone down for 8 hours and your phone drained 57% battery on idle for FR008? I find that very hard to believe because I have set my phone down over night and it drained 2% of my battery if even that. FR008 has shown the best battery life to me over the entire FR series. As of right now, my battery has been off charger for 6 hours, and Ive used the internet, wifi, and light texting with my battery at 100% still.
Edit: Im also using SetCPU...I dont know how much of a difference that would make, but there should be a difference. Try using SetCPU

FR008 is a battery drainer from hell. I just accept it.
SetCPU slows down my phone to epic proportions--no thanks.

It wasnt just one night - I tested this for 3 nights straight before I made this post -

Here is a note :

I said I have been off the charger for 6 hours. Not necessarily using the phone for 6 hours. I browsed the web for around half an hour and sent about 30 texts since Ive been off the charger. I just dont see how its possible for your phone to drain 57% while youre not using it. What happens when you start using it?

Wow... to use your words "I just don't see how it's possible" that you are still at 100% after sending 30 texts and 30 minutes of web browsing. In my own experience with my 2 month old Aria, even on the stock Aria, that sounds unbelievable. Either that or your battery calibration is way off.

My HTC ARIA with FR008 drain 2% in 8 hours.
Wifi off.
GPS off.

Unique Battery problem

Sorry to start another thread on battery issues but I was unable to find a scenario like mine.
Hey everybody, Im new to the android scene, just got my vibrant less than a month ago. Before that I had an Iphone 3g. So far I like the phone but the battery life is horrible. When I surf the internet on wifi or 3g I noticed that I use like 3-5% in a matter of 5 mins. Is this normal? I consider myself to be a light-moderate user and have been getting and average of 12 hours or so on my vibrant. Also if it makes any difference when my phone is idle or being used my temperature runs around the high 80's low 90's but when being charged it drops to the low 80's or high 70's. What is going on? How can I get more 20 hours on my phone? With the iphone I used to get an easy 15 hours and still have like 40-50% remaining.

When I first got the vibrant, it had pretty bad battery life, I would lose like 25% while sleeping 8-10 hrs. So light usage would be like a day. Slowly I started to get longer battery life (2 days on light usage). Recently I could get up to like 3.5 days on real light usage. After updating to JI6, max I can get now is like 3 days. I didn't really do much and I tripled my battery life by just giving it time.

Thanks burntrat I guess ill be patient. And I must mention that I am running stock.i was just worried because my battery temperature gets colder when charging and warmer when idle or running.

Hey burntrat or anybody, has your battery ever acted sort of schizophrenic on you? I mean one day I leave it on standby and its drains like 1% in 7-10 hours another day I leave it on standby and it drains 18% in about 4 hours. Whats going on?

My battery has been draining inconsistently lately. It drains faster in the 50-100% level. Under 50%, it feels like it drains slower while doing the same stuff.

if your phone is draining a lot during standby or sleeping. There may be a rogue app out there or an app that didnt shut down properly. (I guess that would mean a rogue app)

@aamir123 and burntrat: maybe you guys need to calibrate your battery? Also the stock rom usually has a lot of bloatware running in the background. Flashing a custom rom oughta do the trick.

How do you recalibrate the battery?
Sent from my SGH-T959 using XDA App

Try this. Download the system panel app from the market. You can set it to monitor your system and it will chart what applications are running and how much they are using the cpu. If you find you have some unnecessary bloatware running in the background download titanium backup and freeze those apps.

There are a lot of different ways mentioned in different forums. Try this:
Let your battery drain all the way to the point when it turns off by itself.
Charge it while its off until its full.
Unplug it, turn the phone on, then plug it in again.
After it reaches 100, unplug the charger and turn your phone off.
Once off, plug it in and let the charging complete.
Once complete, unplug it and turn the phone on. When everything has loaded, turn the phone off (note: no charging involved in this step.)
After it turns off, charge it one last time until 100%. After this, go into recovery and clear battery info (or cache, I forget). There you go
Oh, and its better if you don't download too many apps that monitor battery usage, cpu etc. cuz they will contribute to the battery consumption.

It isn't a good idea to let your battery drain all the way to zero since it is lithium ion. I think skipping that part and just charging it when it's on to full, then off to full, then on to full, then off to full and then wiping battery stats would suffice. Also you need to have clockwork recovery to wipe battery stats.

When the phone turns off by itself, the battery still has some juice left in it to prevent it from losing the ability to charge, if that's what you meant by not a good idea cuz its lithium ion. If thats not what you meant, then please explain why.

Agreed. In my case, I barely lasted 12 hours on moderate use with any of the JI6 2.1 ROMS (Eugene's, Bionix, Fusion, etc). I think after I updated to 2.2, all of the ROMS have been giving me 18+ hours on moderate-heavy use no matter what modem or kernel I use.

So where is the "unique" problem?

[Q] Battery problems... still...

Ok so I know I've posted about my battery before but I still can't get any relief.. I'm running JT .9 and geekniks 12/19 kernel.. the past two nights my battery drained 30% over an 8 hour period, with no one touching it! During both these nights I turned off Auto-Sync, and yes GPS and WIFI are both off..
Just now I had my phone charging and it was at 47%.. I rebooted my phone (just my normal procedure about once a day) and when it came back up a few seconds later it was at 69%!!! What gives?!?! Anyone have any ideas??
I have tried re calibrating the battery by deleting the battery stats method.. I tried calling verizon to get the battery replaced but was told that my battery is acting normal.. ive tried different kernels with no noticiable difference.. if i take my phone off the charger at 100% and send just a few text messages it will be down to 95% within minutes.. im at a loss.. I'll post pics of my battery use screen in a bit but throughout the night i only went 1% without a signal.

Maybe try *228 Option 2 ..... ??
I had a bout of some wicked battery drain and it was because I needed to update my roaming.....

I have the exact same problem. Battery will drain for no apparent reason. I even bought a brand new battery, with still no luck. When I reboot the phone, as you said, something it will jump up 20%. I finally got fed up charging 4 times a day and ordered a refurbished phone. I'll let you know how that one works out.

although Juice Defender turns off your 3g when the screen is off, it also turns on your 3g for 1 minute every 15 minutes, so push notifications will be seen every 15 minutes (which I find totally acceptable to dramatically raise my battery life)
Just an fyi in case you didn't know.

yeah i was aware of that but i also didnt notice my battery life improve enough to use it.. if i would have noticed a dramatic improve i would have kept it.

At first I didn't notice an increase either, but after a day or 2. I get over 50% battery now

I just started charing my phone again.. it was at 70%.. i rebooted my phone and it jumped 14% to 84%... is it possible that the battery meter is just not accurate and when I reboot my phone it recalibrates everything and displays a true reading?

I can't remember where I read it, but I read that the phone doesn't portray an accurate reading. . If you charge to a hundred percent, the phone reduces the amount of power coming in but still shows full till removed from the charger, then it drops fast. Supposedly once it gets down to a certain percentage it starts charging again in bursts. This could explain why rebooting changes your percentage since the OS is showing the inaccurate reading.
I don't know if this is true or not, just something I read.

There's an excellent explanation of this here on xda. The thread is called "Your battery gauge is lying to you (and why that's not such a bad thing)" & I wish I could remember who wrote it so I could give him credit.

I called VZW's Customer Service and told them about my issues and they sent me a refurbished one. Just got it today, and so far, I'm having the exact same issues.

I am only here because a friend of mine is looking to get a Fascinate and I was doing some research for him.
I have an Evo, and I gotta say, you only lost 30% in 8 hours? Lucky you! The Evo, when it first came out would only last about 8 hours off the charger from a full charge, without touching it. The state of things now is a lot better. I can go 16 hours off the charger and still have 70-50% battery left depending on how much I used it.
The biggest changes have been custom undervolted kernels with HAVS, CPU underclocking with screen off, and "SBC" which probably just stands for super battery charge.
The SBC kernels for the Evo fix the issue of the battery dropping to about 87% minutes after taking it off the charger. It changes the charging behavior after full charge, maintains a trickle charge to hold battery voltage at 4.2v instead of burst charging intermittently once "full"
You guys might want to have your kernel developers look over here and probably see if some secrets can be passed along:
http://forum.xda-developers.com/showthread.php?t=876590
There's a neverending cornucopia of battery improvements over in the Evo forum and I'd suggest you guys go make a search over there for "battery" because tons of the same fixes are going to apply here. Good luck

I had a lot of similiar issues with battery life, and I found different kernels and roms have a huge effect on the battery:
Every StupidFast kernel I tried would *significantly* increase battery drain over stock. I'm talking 4-5% per hour overnight with the phone idle and not being touched or doing anything whatsoever - no GPS, no Bluetooth, no WiFi, no apps running, just sitting there.
Every BlackHole ROM I tried would do pretty much the same, although not quite as drastic.
JT's SuperClean was consistently very good on the battery.
On DI01, I was using SuperClean .4 on the stock kernel and getting a solid 24 hours on a charge. With DJ05, there is no stock kernel, and I had issues with SuperClean and signal strength, so I'm using the 12/12 kernel with the stock rom (debloated) and I'm getting 72 hours on a charge with conservative use and easily 48 hours with moderate use.
If you're using StupidFast, I'd suggest flashing one of JT's kernels or stock (if you're still on DI01) and see what difference it makes.

I finally am getting decent battery life.. I did a clean wipe and installed black hole 2.4 with jt's 11/29 kernel and have noticed a great improvement! Only problem is I get the audio popping with this kernel but I'll live with that as long as my battery is better.

So I've gotten my second refurbished fascinate from Verizon, and my battery life is still atrocious. However, how much does signal strength affect battery life? I get a dismal signal at my house, where my battery seems to drain like crazy. Can anyone confirm the relation?

They are directly related. If your phone if constantly trying to find a signal then this will drain your battery. Are you rooted, or totally stock?

battery problem kyrillos Rom

i use the latest release, 3.3 version and my battery drains in like 10 hrs of normal usage...
the worst part is that upto 95% of battery is consumed just by display?
i used to get 2 days of battery backup previously on the official Rom.
i tried re flashing kyrillos Rom yesterday and i still get the same problem :’(
is there something i am missing?
or should i wait for atleast 1 week after flashing?

I don't know, but you can also install Juice devender from the market
I like that app. Now the battery has a longer life: 2 days.

The battery seems to be a problem indeed with our devices. Mine was on 5% for 12hrs yesterday.
I've read advice from Lestat, I think, to charge the battery completely before flashing.
I've yet to test it though.

awesome bro, will reply here with the results soon......

does some1 know a fix to show my battery in units in stead of dozens? srry for my english^^

boom....battery at 60%, 25 hours and still.running ( but can only say its because of this when i get home....because right now my cell phone is in airplane mode)

thanks
i think i know why i am loosing battery very fast

It may have to do with cpu scaling also.I installed cpu master and saw that the cpu is always on 667mhz and not down-scaling when not in use.
Kyrillos 3.3 rom

try using SetCPU...

This depends on the network you use, but you can set your phone to use only GSM network or only WCDMA network in the Mobile network settings, if you are located in area where your network switches constantly because of a weak signal your battery will drain itself because of constant refreshing and switching between GSM and WCDMA networks. WCDMA (3G) network uses more battery even if not switching.

Thanks, mine is set to GSM only, since i don't use 3G..
I tested my phone again now for the past two days and found out that it comes for like 20-24 hrs in moderate (daily usage), which is ok for me....
the battery first reduces to 80% in the first 1 hour (even with minimum usage, don't know why this happens), and then it stays at 80-60% for like 15-16 hrs...

I got this problem in Kyrillos 3.0beta version...but now in 3.3 its fine...i can use mine till 2.5 days...widout task manager!!! :-/ i dunno...!!! Juicedefender works cool for sum ppl!!!! the oder solution try Indroid 3.0 - it has better battery backup!

You should callibrate your battery with one of the callibration apps, or charge to 100% and then delete battery stats file manualy. Then discarge your battery completely so the phone switches off. The next cycle should be better. Those first 20% percent do go faster than the rest of the battery.

I installed the calibration app. It said i have to charge it till 100 % and then click calibrate....
I did and now iam 50% in just 7 hours....
So should i let the phone discharge completely?
By the way i flashed with jpm earlier with half battery left....

Guys, all in all i blv its rom specific problem..i m tryin the battery calibration app...meanwhile have a look at this article...

clarkkov said:
After calibration one more cycle will be short. The next cycle will be at least double battery life. I get 30+ hours with moderate use (wifi, calls, sms, light games with GSM non-stop) now. I can also recommend Juice defender as an aid for battery conser ation. setCPU doesn't help.

true , true, true thanks for confirming

still 30 hours isnt enough, its roughly a day.
With 2.1 original firmware and data activated all day i could get 50hrs minimum of battery life.
I'm done with this phone, done trying different roms, calibrating batteries, charging and discharges in less than a day.
i think this phone rocks, except its battery life sucks!
im selling it to change for something with better battery, maybe bb?

Battery problems is from ext4! You can convert all partitions to ext2 with normal battery life but with more chances for data to lost if you remove the battery!

thanks for your reply, do you mean this battery problem doesn't occur in stock 2.2 recently released ?

Lollipop battery issues

Hey guys i got a s4 for free a few weeks ago and the battery was having issues so i brought a new battery from Samsung for $50. I guess the phone is $50 now huh, still that's a good price. Anyway i have an improvement in standby time over the old battery that seemed to drain no matter what, but i only get around 2hrs to 3hrs screen on time full brightness with a mix of auto. The phone tends to get warm when its below 40% power. Also using the phone drains it at a fast rate, but standby only 1% per 8mins or so witch is good. Im backing up with twrp and titanium backup, ive tried recalibration, and im about to do a factory reset on this (stock touchwiz)

Battery calibration apps are a placebo.
Anyway, let me tell you a little story:
2 weeks ago I watched a 2 hour movie on my phone. Started from 100% ans towards the end of the movie I was left with about 50% battery.
Screen brightness was around 60%, WiFi was enabled and the mobile reception was 4G.
All things considered I would assume I can get 4 hours SOT, since it took 2 hours to get from 100 to 50.
This is on a custom rom and battery oriented kernel settings.
Also take into account that I was watching a movie, so the CPU was idling most of the time. Doing tasks and switching from one app to another drives the CPU up.
Your screen-on time seems acceptable to me. I have to mention that my battery is one and a half years old, but I always took good care of it (I never let it discharge too much and never left it charge too much, as both of those, over time, can reduce its storage capacity).

Im using Albe95 rom with a custom kernal and the battery is draining slightly less, ive reduced my brightness to 60% and its drained from 100% to 77% in standby and extremely light use in 6hrs (about 4hrs standby drained 6% and 2 hrs of on off use every now and then drained about 17%. I guess im used to my old LG L70 D320n witch could hold up at full brightness forever. Will Cyanogenmod 13 bring much improvement for me?

I don't know. Maybe Optimized CM13 because it has a custom kernel and you can select battery or performance profiles.

You won't miraculously get 5-6 hours SOT even if the battery is new.
Maybe with lowest brightness, WiFi and mobile data off you will.
Underclocking and undevolting might help a little, but I don't see anyway of getting more than 5 hours.

There's a guide in the general section, _Bon_Bon's tweaks.., Something along those lines is the title.
It has a guide on how to increase battery life.
The guide is based on alucard kernel, though.
Alucard kernel is available for any 5.0 and 5.1 roms. But there is no public build for android 6.
Only JDCTeam roms have alucard kernel for android 6. Those roms are Optimized CM13 and AOSP 6.0 rom.

Ok so slowly things have improved but today when it was at 9% (6:30pm charged this morning) it froze up and i pulled the battery. Then it jumped down to 2% at restart! This has happened before (cant remember if it was on stock rom or the note 5 rom im using on it now) from 40% freeze, pull battery, restart, 22%! Any idea why this happens. I talked to samsung about the battery performance and they just wanted me to send the phone too as "its not just the battery" just for more money instead of honering their 3 month ****ty warranty! Stick it samsung my next phone will be lg like the rest, even though i only just brought this damn phone

The freezes might be caused by CPU undervolting, if you did any.
But the battery percentage dropping suddenly is a sign of a bad battery. It might drop 2 or 3% during the boot up, but not 20%.

Samsung say the phone is the problem. Today i got to 40% and it jumped to 30% within 20 mins. Then i pulled the battery and started the phone up, repeating this multiple times to see the battery percentage. It jumped between 24% 15% and 19% up and down each time i pulled battery and restarted (no crashing just to see what happens). Is this enough to tell Samsung ITS NOT MY PHONE.

Apparently they refuse to accept the possibility that they might have sold you a faulty battery, so they blame the phone.
I don't see how the phone might drain the battery from a hardware perspective.
It's possible from a software perspective, but since you changed roms it is unlikely to be software related.
Did you install any apps to check if the phone enters deep sleep? Or if there is anything keeping the CPU at max frequency?

Ok ive done it a few more times and it seems to possibly be a calibration issue. But ive calibrated it multiple times before

How did you calibrate it?
Battery calibration apps are a placebo. What they do is they delete the batterystats.bin file which, as stated by a Google engineer, has no relation to battery life or the battery display.
Also, that file gets deleted automatically at every reboot by android itself.
What you could do is:
First let your battery fully discharge, until the phone turns off. Then try to turn it back on. If it turns on, proceed to use it until it turns off again. Do this until the phone won't turn on again.
Now the battery is completely empty and you can plug it in to charge. Let it charge to 100% without interruptions.
Take into account that it can take up to 3 hours to fully charge.

Haha done this before to no avail. Will do again but i noticed battery life is generally better if i leave it charging for 10hours after its charged fully. Instead of taking it off when it gets to 100% but i think a long worded and very angry email is about to be sent to the Samsung repair centre
Sent from my LG-D320n using Tapatalk

on my travels around google I've read many times that with lithium batteries you NEVER want to completely discharge or overcharge them. give it 10 minutes extra once fully charged, not more. you're damaging the poles or terminals or something I can't remember fully when at either extreme. all you achieve is a shorter lifespan for your battery.
discharge it until it turns off but never until it can't turn on again. it has a chip in the battery that needs to stay powered too.
