Show off your battery life!

This is my moderate use. Few web here and there facebook, some calls/texts and instant messaging for a good 3hrs
I am running cog 2.2b5
Just wanted to compare battery life and post the rom you are running too
Sent from my SAMSUNG-SGH-I897 using XDA App

my battery life sucks. i get about 10% per hour....

What Rom are you using?

yeah my batt isn't too great either. 2 days on Cog V5 now. Each day has been roughly 10hrs with about 4.2hrs use. Each day I ended with maybe 1-2% left.
Is this normal? Froyo didn't help a bit. In fact it may have made it slightly worse.

When I flashed b5 ... it was great. Then I found my gps sucks on it so I flashed again and I found that the battery drains like water 1% every 5 mins! ( Idk what's going there) Then, I flashed again and the above post is my result and my gps still sucks. So maybe if you flash it again it might help. I re partitioned in odin as well.

I am using Froyo (JI6) with lagfix and I get a consistatnt 12+ hours of moderate use. I usually charge my phone every three days.

Cog 2.1.7
I have to charge my phone every night. I have used multiple roms from cog 2.1 and even cog 2.2 as well as stock and it all seems the same.

There is no way that is an accurate picture... there is no way you made phone calls or used the facebook app without it showing up in usage.... u may have gotten 40% out of 12hrs but you did nothing with your phone

I use tons of apps on my phone and the only things the show up in my battery usage are: Display, cell standby, phone idle and voice calls.

you need to recalibrate your batteries or flash from 100% as DesignGears had mentioned earlier.
i now flash from 100% batt life when upgrading to new ROMs. or do a search for battery calibration.

Not sure how to do a screen shot but Im running 2.2 beta 5 and I thought battery life sucked but it was because I was checking it constantly and playing with GPS.
Today, after recalibrating battery stats two nights ago I have dropped 3% in 3 hrs of standby and very, very light use.
Also, to recalibrate battery stats I downloaded terminal emulator and did the following
su
rm /data/system/batterystats.bin
I had drained it fully down to 1-2%, did the above commands, plugged it in and charged to 100%. You must be rooted to do it this way I would think since Im using su for superuser.

Yea, I recalibrate the battery on my 2nd flash. the first flash my battery was draining literally 1% per minute. So I reflashed (I thought something went wrong on my 1st flash) and recalibrated now it's normal again.
gocats7: Yup cog comes rooted

Cognition is awesome. With all the features built in, the att crapware stripped out I dont see myself ever running a stock ROM again. In regards to battery though, I think its at least as good as stock if not better. I havent had 2.2 beta 5 loaded long enough to really tell.

I've never had poor battery life. I did have that "new phone syndrome" when I got it and had to charge it a lot. But now I'm going around a day and a half on a charge with moderate use. I use wifi everywhere I can and try to minimize the time the screen stays on.

Have you found that wifi has been helping your battery life? When I have mine on I lose battery at ~5-10% an hour. With it off I lose 1-2% an hour. I have to switch it off nightly so that I don't have to charge my phone again in the morning.

Just the thread I was looking for...
I just recently bought a captivate that had the battery problems it seems so many are having with random shutdowns etc. I would get maybe 12 hours before getting the recharge notice. And that is with very little use. So, along with the advice from these forums, I had it replaced within my 30 days and immediately noticed a difference in the way the phone felt(if that even makes sense). It seemed like the screws were tighter, it was cleaner and it way out performed my previous captivate. Had me thinking I was given a display model or something.
So, to keep it short....I just plugged in after (for me) a very impressive 64 hour strech with moderate useage, some gaming and movie watching. Could not be happier with this phone right now. I cannot for the life of me figure out how such an impressive spec'd phone can use so very little power while locked. It makes me feel like a proud parent...lol.
I <3 My Captivate...

I have actually found my battery lasts longer with wifi on. I only turn it off when I leave the house. For me the wifi seems to be a lot more power/data efficient then my data connection. I can use the phone all day on wifi and still have 20% left at the end of the day whereas when I've been out all day long using data I can barely make it home without it *****ing at me to charge the phone.

I have had the best battery life yet with Cog 2.2 Beta 5.5 and migrating my Exchange server to Google Apps Premium so I do not need to use stock corporate email app anymore. I am pretty happy with this so far although I have only used the new beta for a day so far.
As a bonus, I am even using Live Wallpaper.

27hr, just dropped below 30%. Love it

[Q] Best battery life?

Hi,
I just recently bought my Inspire and rooted/s-off/eng s-off.
I flashed Android Revolution and I can't stand that I can't have my phone for more than 6 hours before 15% battery.
Is there any other ROMs that have better battery life? I'd rather have something like an optimized stock, but I really would love better battery life.
If you're wondering, I don't do a lot on my phone--just music, texting, and mild web. No video, and some e-mail.
Thanks~

For me, CM7 has better battery life than AR.
It's AOSP though so no sense. Though honestly I don't miss sense at all. In my experience the only feature that sense has over stock is the dialer and camera.

How long were you using Revolution? ROM's need some time to even out in the OS. At first they'll rip through the battery like nobodys business. Also, did you reset the battery stats? I'm pretty sure that is in the Revolutions FAQs. I could be wrong though. Also, the ROM in my sig is a great one to try. He also had a sense version if that's your bag.

Phone Battery usage statistics
I flashed CoreDroid V5.1 two days ago, and i'm sad to say i'm experiencing similar DISMAL battery performance. I've ran specific tests on it all day today, and this is what i have seen thus far:
08:12 - 95% - Airplane mode ON
09:46 - 91%
11:32 - 86%
12:30 - 83% - Airplane mode OFF
13:27 - 73%
14:33 - 62% - Airplane mode ON
16:30 - 44%
These stats were taken with the phone NOT IN USE. The screen was off and it was sitting on my desk. So, as you can see from the list above:
with AIRPLANE MODE ON - a loss of ~3-4% per hour
with AIRPLANE MODE OFF - a loss of ~10% per hour!
This is patently ridiculous!
When airplane mode is on and the phone is not in use, it should be basically on standby, using maybe a percent every hour or two.
When airplane mode is off, 10% /per hour?! That is just INSANE! No WONDER i can't get until even 7pm before my phone is dead!
If it can be determined what is sucking down the battery with Airplane Mode ON, and that 3-4% is eliminated, then the phone should have no problem lasting >14 hours.
(As a note, i saw similar performance before i rooted, so it's not just the ROM)

Moved as not android development.

I don't know if it's just how Sense works, but whenever I view the Applications in Settings, ALL my apps are running, ALL the time.
I don't remember it being the case with my Captivate, though..

Charge your battery till it completely charged. Turn the phone off and boot into ClockMod Recovery. Wipe the battery stats and hopefully that should help with the battery.

If i leave my phone alone over night while i sleep after 8 hours it will be at 93/94%.
Download an app called CurrentWidget. It will tell you how much your battery is being used.
Remember to enable logging so you can check the log latter on your sd card .
With my phone idle I normally get ~3mA or less per minute with spikes of ~160mA once an hour or so.
The max "Screen On" time is about 2 hours per charge.
There is also an app called Traffic Monitor Widget to see how much data each app is using.
These may help you understand what your battery drains so fast.

I dunno really. I just took two more screen caps from today. Just my general days usage. I've had the phone for only a week now so I expect the battery to break in a bit more like my nexus did. I was a bit worried about the battery life and this thing lasting me throughout the day but I have been impressed so far. I never even used it with the stock ROM so I can't compare, I dislike Sense.

I've been off the charger for 13hours. I'm at 50% with 1h10min screen on time too. I've had mine for about two weeks now.
Sent from my HTC Inspire 4G

I'm running coredroid 5.1 and I fail to see that I'm loosing 10% an hour. Here's how my day was in battery faintly remembering. Woke up at 9:30 took of charger and left for work by 10. From then to I say around 1 I had around 90% only cause I was messing with my build.prop so I was restarting my phone like 20 times doing some test. Also I was ebbing a lot to look for info on what I was doing. And near the end of work around 5 I had even been playing music and games. And was around the 60% I wanna say in the high 60% I played with my phone a lot today and as of right now the same day I'm talking about I'm at 44% and been on my phone like crazy even rebooted a few times again. From what I have been doing to my phone I highly don't see how u could loose so much battery. So from now 10 to to 8 I'm at 44% that 10 hours I was playing with my phone like crazy.
Tips. Use recommended radio's. Charge to 100% clear battery bin. Also give it a few days for the Rom to get built in a little bit. also go download frail CPU its free. It'll help you save some juice when screen is off. Hope this helped.

thats because your phone is sitting in standyby 90% of the time. I've never checked my battery use and NOT had display at the very top using at least 50%. Its not wonder your battery life is great

I have been on many Roms but cm7 rc4 is the best for me. I get about 18 hrs of life with normal usage and gaming. I think Sense is the culprit on other ROMS. Also the free memory on cm7 is 200mb more than on Sense. And this is 90% of the time for me.
Inspired from my Inspire 4G using XDA Premium App

I don't think you can beat miui. Pulling 1-4 per min. Of all the roms, I tried this is the best. Ginger with OC kernels too.
Sent from my HTC Desire HD using XDA Premium App

If your talking about mA per minute. I get that with my non rooted inspire.
Sent from my HTC Inspire 4G

I have noticed something funny about the battery stats on different ROMs. In particular, on CM7, I would never get display as using more than about 10%. On the other hand, when I am running stock rooted ROM, my display always uses about 60%. This is all with similar usage patterns and similar brightness settings. What is going on there I wonder?

I have also never seen my display less than 40%! Even today.
Attached are screen caps of my usage, based on what was happening earlier.
So lets see, display was on 1 hour out of 15 hours. And that = 40%. yea. i call bull****.
Thank you to all for your suggestions thus far. I will try them all out and report back what i have found!

I am heaving very good battery life with CorDroid 5.1 But I also had good battery life with Rev roms. When I am in a fringe service area I switch to GSM only and it more than doubles my battery life with the radio I am using. If I dont need the high speed I leave it off if it is not a strong signal.

Maximizing Battery Life

What do you guys do to maximize your battery life? I just can't seem to get decent life. Average is probably 5 hours with heavy usage.
Any recommendations?
Sorry if there is already a thread, I don't have a computer right now and I don't think I can search on tapatalk.

The usual - brightness as low as you can stand, radios not in use turned off, screen timeout 15 seconds, 200-1400 conservative governor in SetCPU.
Search AutoKiller in the market -- choose "optimal" profile, so far has given me an extra two hours today over what I got yesterday.

5h of heavy use is good already.
You can tweak your idle batt life, 2g-only, undervolted kernel, avoiding power hungry rom.

Idle battery life is just amazing with stock... just test it over night, 6hrs get 2/3% for me.
I can get 30hrs with 4hrs with screen on, the screen is the key here, i can get 5hrs with 4hrs with screen on too. ;o)

Try a kernel that is made to optimise batt life with display active, like the XTEUV92 Trinity kernel.

I tried almost every single combination of rom + kernel. And for me, pure stock has the best battery life, by far.
But i'm getting bored and should flash something... )
Ps: afaik trinity doesnt work with stock. Did it change?

See my signature, stock (rooted and removed soom Google apps) with Trinity, works together just fine

How would you define "heavy" usage?
Also, what does your "battery use" stats say? (Settings - About Phone - Battery Use)
5 hours of truly heavy usage (online gaming, for instance) is actually to be expected.

You can create a custom prl setting. Turn wifi to never sleep when you're at home... Have the prl to auto *CDMA or GSM* Which ever your network is on. (This goes to all Nexus S. users). So you have wifi on with a signal and 3g off. The phone stays in 2g for calls and uses wifi for data. Turn off google location services while your at home, turn off roaming, turn all of that off. I get about 13 hours of battery life with heavy usage. People think wifi drains your battery but it doesn't if you have mobile data turned off. When you have 3g turned on it's constantly searching for a better connection. If you have wifi on and a strong connection it isn't constantly polling.

are there any charging habits that would help prolong battery life? I usually just charge my phone every night cause, if I remember correctly, these batteries don't have a memory or anything. anyone know if that is the smartest thing to do?

I hope you don't mean overnight. I don't know if phones have auto-cutoff feature (a la laptops), but it's safer just not to charge overnight.
I personally use an extension that has a timer built-in. Nifty. Set the timer, plug the phone in, it will automatically start and stop the charging at the predetermined times. I usually time the charging to end right before I wake up, so the battery doesn't stay fully charged for too long. I heard batteries corrode faster when they're fully charged.
When my battery life starts getting shorter than usual, I let them drain until the phone turns off automatically (well I actually try not to get to that point, but seldom succeeded ), and as soon as possible charge it until full.
Usually the battery holds longer then. It has something to do with teaching the battery about the true empty and true full.. or something.....
AFAIK. CMIIW.

doesn't the nexus s have a built in cut-off feature so it will only charge to 95% though? I figure that would take care of the full charge issue. i'm also not sure if lithium ion batteries have a memory, but you could always reset the battery stats if you're on root to compensate for the whole draining and fully charging thing.

Battery stats! That's the word I was looking for No I wasn't referring to the memory effect
I don't know what would happen when the cut-off feature kicks up. My Nexus S still shows a charging icon even a while after full, so I don't wanna risk it.
The best way is by touching the charger unit after a while and see if it's warm/hot. If it is, it's still charging. But you gotta give it time to cool down first (after it's finished charging) Haven't gotten around to it, though. Always forgot to check the charger

lol, I know that my phone for sure won't charge to 100% from watching it, so even after a night of charging it's still at 95%. I've read a few explanations on this forum about the whole not fully charging thing too, so i'm pretty sure that it's like that on purpose.

Cell Standby Battery Drain

I've searched about a million times in 900 different threads, but I still can't find a fix to this issue.
I first noticed this when I flashed MIUI onto my phone. I would get cell standby and cell idle at about 40-50% of battery usage each. Display wouldn't even be shown on the usage! I then figured MIUI wasn't worth it to me, so I flashed CM7. I tried both morfic's and faux's many kernels, nothing seemed to fix the issue. If I would turn the airplane mode on, I'd get battery drain of only like 2%/hour.
So I figured there was something wrong with the CM7 port, so I tried g2xtreme and other GB ROMs, same thing. Finally, I just checked a froyo ROM, same thing again!
So at this point I'm clueless and thinking the phone is completely a POS, but anyways. I'm about to nandroid restore stock 2.2 firmware, and try updating through the LG Mobile Support Tool.
But I have my doubts that this will fix it. I'm curious though if maybe I'm getting this drain because I'm with WIND Mobile in Canada? And this is for the T-Mobile G2X (they're the same phone and both companies use the same radio frequencies). But maybe there's something written in these ROMs to tell the phone to look for the T-Mobile network? Which I obviously won't be able to find in Canada.
Can someone help me locate these settings, if they exist? Or can someone with a Wind phone maybe toss me the WIND stock firmware? Or let me know what ROM they're using without said issue?
Thanks guys!
Edit:: In low signal areas the phone drains like 15-20% per hour, in high signal areas the phone is still pulling like 8%-10% an hour and I'm not even using it! And the weird thing is it only shows 1% time without signal! Something is seriously wrong with this firmware.

Search for betterbatterystats on XDA, install it, enable battery monitoring in MIUI (if that's your daily rom), leave your phone alone for a few hours, then open BBS and look at the partial wakelocks under "since unplugged." There you'll see what's killing your battery.
Everyone experiences worse battery life when reception is bad, but you are still getting terrible drainage in good areas, which means there's something other than reception killing your battery.

I tried that before, and had a crapload of apps "frozen" with titanium backup.
I'm going to try this again, and I'll post a screenshot this time because I don't think I actually understood what betterbattery stats was trying to tell me last time.
If anyone can help me decode it later that would be great!

Just noticed that there's barely anything under partial wakelock that's noticeable.. RIJL Telephony is the highest with 1m 1s 15%.
But it's not increasing very much, only when I get a text message. However, I've dropped about 7% since my last message, and cell standby is increasing climbing up my battery usage from 33% to 42%. It went from 620uah to 657uah.
Edit:: I reset battery stats cause I was unsure if it was corrupted stats. I started at 17% 40 minutes later I'm at 12%. Phone was off 90% of the time. I made a 2.5 minute call and it used 41uah, while cell standby still dominated with 65uah.
However, I turned my phone on for 5 minutes, making total usage 45 minutes, but had the brightness set to max, and in that five minutes it only used 1uah.
Am I missing something here? At this point I don't know if my numbers are normal or not anymore... I'm going to try draining the battery, charging to full, wiping battery stats, and calibrating and see what happens but 65uah to 1uah is a huge difference, I would've thought display would use a bit more than that.

I noticed this morning that having the phone with airplane mode OFF, that my battery dropped 10% in 57 minutes, and after turning the airplane mode ON, the battery dropped 1% in the next hour and 30 minutes. I checked battery stats and nothing was waking up my phone. Anyone have any other suggestions?
I'm going to flash miui and leave it without any apps installed then try this experiment again.

I find these threads interesting because I am always looking for better battery life.
I am running EB 2.3.3
I uninstalled Set CPU and uninstalled Juice Defender. From my experience both hurt my battery life.
I never bothered to measure in airplane mode, because i use my phone to much.
My battery life improved dramatically during stand-by. 1% to 2% drop per hour with wifi on and a slightly bigger drop with wifi off.
I completely wiped the phone before installing EB and the used Titanium Backup to reinstall my apps without the data. I believe some of my previous battery life issues came from restoring data from certain apps.

I have the same phone/carrier. Do you leave 3G turned on? I feel it rapes my battery throughout the day. When I turned it off, it lasts pretty long.
Another problem I have though, is the drain when it is OFF. I went to bed with it at 90% juice and turned it off. I woke up 8 hours later, and it was at 65% when I turned it on. wtf. This only happens sometimes thou.. Other times it doesn't drop too much.

I experience the exact same issue. But for some reason my battery life is more or less the same with 3g off. So I feel like my phone is constantly searching for a different signal or something? I mean if airplane mode affects my battery life that drastically reducing consumption by like 9%/hour then there must be something up

Everyone who's been telling my phone is not sleeping is correct.
Only program is is that my phone's battery stats doesn't say which app is waking the phone? It lists Telephony as #1 with 1m 1s of awake time, and everything else is minuscule. There's gotta be something the phone isn't telling me :S Could it possibly be a hardware issue?
Or is there a better way I can narrow down this issue? I'm in the process of removing all apps.

Just curious, did you 'train' your battery?

Nope, but it's Li-Ion and my impression was these do not need to be trained.
I just emptied it to complete 0 yesterday, and charged it to complete 100% then calibrated it. Today though it was still horrible battery life until I completely wiped and flashed MIUI 1.9.23 then Trinity kernel brand new. I'm installing apps 1 by 1 to see which one caused me so much darn grief :S

All batteries are Li-ion nowadays, but I still feel after 'training' my battery for a week, they last substantially longer than new ones, fresh out the plastic.

Yes, battery drain is fixed. Also, I was on a completely different baseband for some reason, I was on the o2x baseband, fixed that JUST now, I think that was a part of the reason I was draining my battery like instantly. It was probably looking for a GSM signal!
Thank you for all your help

A simple *#*#4636#*#* can change that.

Yeah I set it to WCDMA Only. Battery life has been awesome lately.

Battery life problems.

Hello, I'm currently running cm 9, however the battery life is just awful
When the phone is on sleep it loses like 1 percent every 5-10 minutes
I am using an extended battery as well, please tell me what to do I was on GB before and the battery was outstanding, I could go on one charge the whole day with heavy usage, now i dont think I can make it through the day with light usage on this
thank you
EDIT: This could be a sleep problem, because when the device is on, the battery is normal

If you flashed the Feb 27 cm9 you should flash proton kernel so you can watch videos. Battery life isn't as good as gb no matter what you do. Also give it some time to settle in. It takes more than a couple hours.

alright thank you... I just flashed the newest version of cm9 a few hours ago, I was flashing a bunch of roms and this one seemed the best... do you know how to force a device into deep sleep cause that seems to be the problem i believe

OK I was just on 20 percent, then i rebooted my phone, and now im on 2 percent... im seriously considering going back to gb

Sounds more like a battery thing? With CM9.? + Proton I'm getting at least a day* with light use. Maybe a bad app or combo of apps? What does BBS say is eating the charge?
* - I say at least a day because I can't not use it for that long.

just the screen and the android system... very interesting thing though is happening
I'm running a bunch of quadrants to get the battery down to 0, and the battery is all the way down to 1%, however it's been on 1% for like 6 quadrant tests... maybe its just a problem with the indicator, however another indicator also says it's at 1%... very interesting

If you are on CM9, I suggest you flash Hefe or Proton.
I use Hefe because according to the posts being made it puts your phone into deep sleep, which means longer battery life.

Definitely a battery problem. This happens to me on one of my batteries but not on another. Time to buy a new one. I haven't tested it fully but it does appear to be just a display issue. Sometimes the bad battery will make the phone display 1% but it will still act as if it had way more than 1% charge left. I haven't done any testing on that regard but that's what it appears to do.

I don't believe it to be a battery problem, because I've been on GB with absolutely no problems and exceptional battery... I just upgraded to ics not long ago, and the battery life instantly screwed up

Have you set the cpu governor to anything silly like performance?
Have you let it charge up fully at least once?
Search xda for "better battery stats" app, use it to see if you're getting deep sleep.

Flash hefe over release 8 and youll have a little better battery. Proton doesnt deep sleep

Proton DOES deep sleep. That was one of its major features.
Certain scheduler/governor combinations work better on different kernels, though. If the specific one you like most sleeps better on Hefe, great. If the one you like does best on Proton, great. Just be aware that most issues are either physical or user-inflicted...
In this case, your battery is almost certainly dying. The variance in power over a reboot is a definite tell that your battery is probably swollen. If you can spin it on a table, the cells are starting to die. This does not mean you can't keep using it, but it does mean that your battery life will be irregular. It also means that you'll have significantly "higher" battery levels if you reboot the phone with external power connected, but the battery will discharge very quickly if it hasn't actually reached whatever level it believes it should be at.
