Info about my battery life

My battery seems to be REALLY bad. Worse than most peoples from what i gather from reading threads. I get about 8 hours from a full charge with minimal use. It seems that my screen is taking up most of the battery, according to my battery use page.... Any one else having major battery drain like I am??

My display is taking a huge percentage as well. Everything else is low percentages. Don't know why. My screen is always either on auto brightness or completely dim.

Give it a while and a few recharges. It should get better. Same thing happened to me. It's slowly getting better. I have it about a week now.

I was getting 7 to 8 hours at first, had my phone almost 2 weeks now and am now getting just under 20 hours with moderate use.
Give it time. My sensation has far better battery life compared with my DHD.

Peeps, you missed most important thing. Look at the AWAKE line. Either OP is playing a lot with th phone, or something is not letting it sleep.

Yeah, the battery really plummets when you actually use the phone (even on low brightness) but it idles quite efficiently at least...

Did u try juice defender? Just asking ify bout the sensation dnt knw either to get it or wait for sumthing else

Would help if you used proper language.

Yeah, noticed same thing

I downloaded juice defender beta? whatever the free one was. To me that app does not have a good layout at all, either that or I was missing something. There dont seem to be any personalization settings at all. I dont trust apps to work when they just say "im doing something!!" ya know?
Now that I think about it on that charge I was playing music while I worked on my car for a while, that would explain the awake time. Even without doing that battery life is still really bad and the screen takes up 80%+. I will post another pic after my battery dies today. Dont plan on using it much so hopefully it will last longer.
That is good news about life getting better after a week or two though cause 8 hours with moderate use is unacceptable. My MT4G got a good 24 hours with pretty heavy use, I expect this thing to get at least half that.

i use juice defender and under normal use and a few hours of pandora streaming on wifi im at 35 hours at 40% battery

My phone was also drained like madness, within 6 hours it was empty, even if I didn't do anything with it. At the moment it is better, I did a factory reset through the startup of the phone (turn phone off, remove batt, place batt, hold volume down and push on/off button). There is an option to factory reset.
Strange thing was that when I turned off my phone before the factory reset, it was telling 34% batt. Right after the factory reset is was at 89% ???
I use Battery Status Bar app to display my batt in percentage...
But the good news is, my problem is now solved. Battery lasts for more than a day at normal use and 6-8 hours while very actively handeling it.
Looks like it was a reading wrong information or something...

Got 11 hours out of a battery today. So far its been charging for 4.5 hours and is at 94% charge. Takes about half as long to charge it as it does to kill it!
I will give juice defender a try. Seems like it works for a lot of people.

I had same kind of long charging last night. Battery died at about 7:30pm. I plugged it and did not turn the power on. Went to play some ice hockey and after that I turned the power on again at about 10:10pm and it was still charging. At about 11:20pm(still charging) I unplugged for a couple of seconds to see the specs of the charger and then plugged back, surprisingly percentage jumped to 100. It was still on 100 this morning at about 8:00am.
Now I found out that phones own battery monitor tells me that time on battery is roughly 8 hours But when I check the time from Battery Indicator it tells me that time on battery is roughly 15 hours, which is correct.

Seems that a lot of people are getting false battery readings, me included. I did a factory reset last night and this seemed to fix this, at least until now it seems to report correct (realistic) values. I haven't charged the battery after the reset so we will see if charging messes it up again...
I hope this is a software problem, i really don't want to exchange my phone, i don't have any of the other problems.

what sort of battery times are acceptable for this phone? many are suggesting factory resets and all i wonder if i should do it or not. if i charge the phone overnight it goes to power saver mode usually say 8-9pm and then the power saver mode (basically dim screen and no gps wifi remains on) is managing to hold the power till i go to bed and charge it. is this ok?
juice defender seems to be recommended eh? maybe one should should try that before the factory reset. btw if factory reset done whats the best way to restore your phones contacts to how they are now? i mean it took forever to link all the facebook, phone and microsoft exchange contacts and offcourse gmails. dont want to go through that again.

I tried juice defender last night and it didnt seem to help. I lost 45% overnight without me even using the phone! When I fell asleep the battery meter said 100% still and I woke up to 55%. The phone says there is some awake time, wonder what it could be? As much as I dont want to do it I think a factory restore may be an option since nothing else is really helping. Should I wait until the battery is 100% before I reset it?
Some new pics, keep in mind I was asleep for all of this use except for what the screen awake time says.

I would say you battery life isnt that bad, if it lasts a day then it sounds about right. People are saying the batteries last longer after a couple weeks or so. If you do factory reset try and connect to wifi when google is restoring your contacts and such, it makes things go a lot faster.

I managed just over 9 hours on my first charged but I'm recharging it now and it went straight up to 31% when it booted up again :S

Me and my gf both have a Sensation now(i upgraded from HTC Desire, and she a HTC Legend), we are both pleased with the battery on the phones, she uses stock Sense, and i use LauncherPro, though we did learn something from our older phones, the thing that drains battery extremely much is all the notification emails Facebook automatically send(gmail push), these are almost turned off to 100%, next thing is to turn off all syncronisation in the phone you don't use, ex. i use Launcherpro therefore i don't need the phone to update Sense's own weather, and so on.
We both normally charge the phone every night, but i guess my phone would last almost 2 days on days i don't use it that much.
I must say i am extremely satisfied with my phone, the thing that i dislike the most is the camera, or to say it in a different way, if i didn't know the SG2 had a slightly better camera i may have been more satisfied

You should not have anywhere near 100% awake time unless you're using the phone at all times. You have some app that is not shutting down or auto-updating far too often. That's your culprit - find it and your battery life will improve.

What app is this???

[q] why does mobile data cause so much heat!!?

So i relised that when i habe. Mobole data enabled and im browsing the web my phone gets really hot 44C when i have wifi on my phoke doesnt go past 35! Battery drain using mobile data is awful to... Any ideas why?

+1 on this..weird.
Mine also on mobile get as high 47c, while wifi only 34.6c

I want this to be somehow fixed i hate the feel of it when its hot!! Causes my battery to drain more to

The phone getting hot doesn't drain your battery more... the fact that mobile data uses more power than wifi makes your battery drain more. That is also the reason for it getting warm... nearly every smartphone I have had with 3G has done this. Normal.

My dhd never got hot when using mobile data
Sent from my HTC Sensation XE with Beats Audio

Neither did my Hero.
This sucks. My Sensation apparently can only browse the Internet using mobile data for 2.5 hours before the battery dies. I'm pretty sure that's not the case for the SGSII either

My sensation gets pretty hot to, but that wouldnt be such a problem if the batterylife would be good. At the moment my battery drains about 8%/hour when it's idle... so i have 12,5 hours stanby time! that sucks -.- I'm gonna get a Anker battery soon and hope it's gonna get better with that...

If you get 8%/hour drain while idle, and truly idle (i.e. your phone is truly in sleep mode) then you've a faulty model - bring it back

Well i don't know how it was with the stock rom and anything. And i don't have any longtime informations with custom roms, kernels and so on, because i just recently flashed a cr.
But today I unplugged it at 8:30am and it had 100% at 10:30 it had 84% and now it has 70% and from 8:30 to 10:30 i was only on facebook and surfed a little for maybe 10 minutes or so :S
Now I flashed Bricked Kernle v.1.5 i hope that its gonna be better with that.

Do you know if you're phone is actually sleeping when the screen is off? To check, go Settings - About Phone - Battery. Here you can see Up & Awake Time, but to see more accurately, click on Battery Use, then click on the graph. Look at the Awake bars and make sure they correspond to the Screen On bars.

The screen on/off and active bar are almost identical. There are some little tiny active times when the screen is off, but thats probably some syncing...

I think almost every sensation phone users is facing the problem too...including me.
I really hate it when my phone gets heated up and when i put it in my pocket it feels like a boiled egg inside.

Faulty model, return it! On (real) standby (which the image shows you have) you should get only 1-2% battery drain, even on Sensation

Don't think that's true.
For one, there was a few weeks when my phone did not heat up like crazy from normal usage and I could make it last 2 days. Then one day it started heating up like crazy... also plenty people report 2 days battery on moderate usage with Sensation - i.e. no crazy battery drain.

Could it be that my phone is alright and only the battery is faulty? It would suck to return it -.-

It's not a faulty model. There are no known issues with standby drain on any sensation.
Notice the image shows times with poor signal too. Additionally he may have auto sync handling too many accounts.

It's getting better with the ROM I'm using at the moment and i orderd a Anker battery. I hope it's gonna get even better with that beauty

I can't explain any facts, but I really don't think slightly higher battery drain is because of a faulty phone. I've owned two Androids and tinkered extensively with many, many others. Most Android phones seem to be awake similarly to that one user's battery graph. It's normal.

[Q] Battery Life, Return Or Not?

First off, I am loving the phone. It is such a massive leap from the N1 I had been using. While I expected lower battery life, I did not expect to run through 70% of the battery in 4 hours with moderate usage.

I have heard of people getting far better battery life, and have tried the various methods, from charging to 100% then turning the phone off and charging again to 100%, using juice defender ultimate, and even resorting to factory resetting the phone. Still I can't get any kind of good life out of the battery. My question is should I try and get a full replacement for the phone or just the battery? I've only had it sinceblast Thursday, so I know AT&T will happily exchange it, but if yall think it's just the battery, I'd rather just replace that then the whole phone.

Have you found out what is using your battery?.. Even before I rooted and all the other stuff was getting at least 10hr.. now Im getting 24-28hours...
Are you running another ROM other than stock?

Didn't want to root if I needed to return anything, so I am running stock currently. Looking no app seems to be running away and draining all the battery. Everything looks the same as it did on my N1 in terms of what's draining the battery, which is what lead me to believe it's a bad battery possibly.

Well if you do root than TPC's Rom is the best. It comes with kernel and the battery life is outstanding.

I was concerned with battery life at first as well. When I first got this thing I had to plug up 9 hours after I unplugged. So now I am near 30 days with it and the battery seems to have leveled out enough for me to be happy. I got 16 hours on it STOCK no ROOT the other day without plugging in, was at 10% when I finally plugged in. Yesterday I activated Juice Defender again after getting some questions answered. I got 17 hours without a plug in and was still at 25%, so i probably could have gotten 20+ hours if I needed it.
So I am happy now 17+ hours is plenty long enough for me, I always plug in at bedtime anyway.

I'm wondering how many people who are reporting battery issues, if they have calibrated them. Charge your battery all the way, use the phone until the battery dies, then fully charge. This will give a more accurate reading as far percentage used.

There is a new ROM Piret RC1, the battery life is amazing, it has a different Kernel as the one with TPC has it';s problems.
RC1 is clean fast and in 2 hours I used up 4%. Then turned every possible service on used it up like crazy to drain the battery, installing/backing up/ flashing new rom and it took 2 hours with heavy usage to drain from 17%. Just to compare last night I had a TPC ROM and was on WhatsApp for about an Hour and battery went from 85 to 34 %.
Re: Returning the phone.
First once you root you can the same way unroot, make sure first you install a stock ROM.
My friends have the same problem, one with this phone, and others with android phones in general, don;t waist your time returnig. To be safe you also have a year to send it to Samsung to get fixed if there is something wrong with it.
Basically, running apps will kill battery, location services kills it the most, sync not so much, heavy use of data does to (I have LTE plan). Use power saver to start at 70%, configure it right, use the CPU app to manage the speed ondemand.
Most important don't frick out, the andoid phones are like that, the major difference is that Iphone does maybe 20% of what android phone does in standby and many things are not available on Iphone, so the battery is better. You will not get more then a day of use on android if you use it to your benefit. 28H is mostly standby, no sync, no internet usage, just moderate. I used to use Iphone heavy and battery would not last a day.
Get a good data plan, don;t use WI-Fi unless u have too, when syncing with the car plug it in the charger, spend extra $10 get a Samsung cable from them, don;t go for cheap 10 dollar once or even 1 dollar once from China, they are very slow to charge. My cable from the box take 1.5 H to charge to 100.
Hope it helps, please don;t quote me on anything, this is purely based on research and one week usage and trying different things, it's strictly my opinion, don;t expect your phone to last like they use too, it's 21st century and techno in it is overwhelming and needs power. Keep the phone have two cables and enjoy!

This is my first smart phone, after 20 plus years of having cel phones. I try to read before posting any questions.

good habit to get into thanks for that....the search button is your friend.

I have been reading on the battery issues, long before I posted. I have done everything from calibrating, to using juice defender ultimate, to doing a ritualistic dance to try and coax more battery life out of this phone. Still with nothing but 2 phone calls and one quick spelling look up, dead within 8 1/2 hours.
I just got my extra battery and charger from samsung in today, already fully charged up this battery and will see what it can do for a few days. I'm hoping my problems are just a random bad battery. I also factory restored and am running bare minimum on apps just to try and remove all variables. If there still is a problem I will exhange it for another one next week. I just hope they still have some white ones in stock

My battery went completely dead too. I returned mine. Black model though. New one is doing okay so far. Better since it doesn't report 100% battery until a reboot...

Finally went and exchanged it last night. So far I have gotten 9 hours of battery life and am only down to 70%. Better than before, but the vertical lines on the screen are worse on this one than the last.

I have almost the opposite "problem." Not that I'd call it a problem just yet. I had my phone running from about 10am till 1am yesterday. I went to bed and plugged the charger in and it instantly said "battery charged 100%. Remove charger." 15 hours with no drain at all? Granted, I didn't do much with it yesterday but send about 20 text messages.

Going on 32 hours+ battery life and no vertical lines.. bought it when it came out Nov6....

30% in 9 hr's? you need to see what is killing your battery... unless you play games or on the net all day.. that is not good at all..
I lose about 1% an hour..

I don't know what you smoking man but i tried his rom and never had issues. Let me tell you I Have ORD so my suggestion will be based on my usage rather than prediction. I have tried most of the themed/tweaked roms. Don't like stock rom.

Are you like me with battery life?

I'm getting pretty good battery life on bean R2 (I easily average 20+hrs). But no matter which ROM I am on, no matter if I'm getting great or poor battery life, I always start to get on edge once I have dropped below 70%. I start to think, damn there goes battery today. I realize I still have 3/4 of my battery remaining but I just feel this anxiety that my phone is not near full charge.
I let it drain to empty a couple times a month but it becomes almost unbearable when I get down to the last 1/3 of my battery life.
Is it just me?

sounds like you need to turn off percentages. I had this problem until i turned it off. Now i have to go a few steps further to find out what it actually is and that makes me not care as much.

My battery life is HORRIBLE.

Have you tried using an app like GSam Battery Monitor?
I've been able to track down a few issues with that app, including one where I needed to wipe my cache to stop my internal sd card from being continuously scanned.

I always get over 2 hours of screen time over the course of a day. Currently using AOKP Jelly Bean, and it's still the same!

Don't drain your battery. People really need to stop thinking these are the old batteries of yesteryear. Draining your battery will cause it stress and lower it's overall life and charge over time. Draining your battery is causing exactly what you're trying to prevent. Best practice is to let it get to 15-20% and then charge.
On topic, I get anxiety about battery at around 70% too. Mostly because it seems to hit that point pretty fast, but then can last the rest of the day no problem.

Have fun with your new phone and keep a charger on stand by! If you use your phone medium to heavy use you should get to the end of your work day and you can charge it when you get home. Did you get your sd card issue resolved?

Ive found that having a spare battery always charged, along with the spare battery charger handy so I can charge a battery while using my phone, works great for my mental 'battery issues'!

On Synergy 1.3, I have AMAZING battery life! Can usually go 2 days between charges if I wanted to...Unplug the phone at 8am and at midnight, I'm rocking 50-60% still, depending on the day.
GSam Battery Monitor can help find apps that are abnormally draining the battery...But I've found that it too can cause the phone to get stuck in a wake lock...So I don't keep it installed, only use it if I have a weird battery drain issue.

I'm the same way, if not worse. I constantly look at power usage (in miliamps and %/hr). I should just remove all battery widgets and percentages, I almost always have enough battery, just paranoid.

On topic, I get anxiety about battery at around 70% too. Mostly because it seems to hit that point pretty fast, but then can last the rest of the day no problem.

That's weird how they do that.
My phone does the same exact thing with the big 4000+ Hyperion battery. It drops to 70% in what seems like no time at all, then three hours later it is still at 70%. The battery gauge obviously is not very accurate at all.
Right now, my phone has been on for just under 10 hours and says it is at 40%. if I just let it go (I charge it every night) it would run all night and still be at around 40% tomorrow morning.

I am the same way after just installing synergy 1.3 on saturday I have been constantly checking battery percentage. Anytime I change anything I get obsessed with it for a while.

This is what I like to see! Used to not be able to get close to 3 hours screen on.

What did you change to get increased screen time?

Switched to beans custom rom. This will be my first discharge though.

Battery
I've read about the new batteries and not letting them completely discharge, instead recharging when it gets to 15% or so.My battery life was awful, if I was at 45% or less I needed to plug it in before going to bed. This was a daily thing, I charged my phone every night, Well I forgot the other night and woke up to a dead battery. I plugged the phone in and turned it on while charging. I charged it to 100%. This was 2 mornings ago (not been charged since) and I'm just now a 46% with normal usage (for me). I just thought this was interesting and wonder if anyone else has experienced this or can replicate it.

Battery Life
I'm getting smoking battery life, been tethering a good 2/3 hours and been on the phone and answering email add day and checking this site. I am on 1.5 Synengy, and using the Snapdragon CPU script that was posted in one of the forums. I can post the link as I don't have a large enough post count, however I would search the forum and find the mod and use it.
It's amazing, I'm at 51% battery and have not plugged in all day. I unplugged it at 7:30 am Arizona time and it's 4:30pm AZ time.
Try it, it' works.

I get better battery life with than I did with my rezound with extended battery

Here is what I was talking about it's works for me.
Here is the link to the mod I used on my G3 it works amazing, it's a little confusing to enable, but one it's enabled you can rest assured it will work.
You can also change the processor speeds along with the battery save options.
Make sure you read the OP VERY CAREFULLY, it's where all the details are to run the script.

Wow, your cell standby was eating you up. Hope you got that fixed.
As far as battery life, I feel mine is average to good. Cell standby and Android OS account for only 9% and 5% of my battery, the other 52% of it used up is screen.. so I think thats pretty good numbers to see.

Severe Battery Issues... anyone else having this? (results inside)

So one night I left my phone off the charger at 40%... it was about 2am. I woke up at about 6am and the phone was completely dead. 4 hours of STANDBY drained 40%. So I thought I was just imagining things and compared my phone usage stats to my buddies who got the same phone at the same time. Here's a quick comparison... and mind you.. my numbers are after a FRESH factory reset with only stock app updates installed and maybe 2 or 3 of MY apps that I needed. I can't speak to what he's installed, but with these contrasts... I don't think it matters much.
Does anyone have some insight to this, similar experiences? I'm really thinking that I have a bad battery perhaps? I get usage varies by user but I really don't think this much especially considering that I intentionally let my phone just sit uncharged and unused for a good chunk of the day after it hit 100 and I pulled it from the charger.

Maybe an app constantly running in the background?

That's what I thought.... but not after a factory reset?
Here's the Usage Stats from a *#*#4636#*#*.... nothing out of the ordinary

same carrier? Your signal may be horrid in comparison to his.
Could be location, could be carrier. Make sure to take a look. If your phone is struggling to keep a data connection you'll kill your battery easy.

Same carrier, we live down the street from each other. Signal strength according to the *#*#4636#*#* is -92dBm 48asu (whatever the asu part means)

Sorry I don't have anything to add but I had this plague in S7. My battery died very fast.
The S8 has been opposite for me. I was able to get 15 hours out of the battery using it all day (where 8 of it was in a really bad reception area).
I hope you get it sorted out. I could never figure it out with my S7. I did alot of research (all here)

I am planning on bringing it to the AT&T store and presenting my findings to them and demand a replacement. I know that I had no issue chatting AT&T support and getting a replacement but they say that since it's brand new, I need to get support from the AT&T store.

I don't know the battery life on mine is amazing 100% after 8hrs standby. and I was on my phone yesterday for 14hrs doing stuff and that brought me down to 5% from 100. I have most of the gestures and crap that drains the battery off though.
My point is if your not happy with your battery life there maybe something physically wrong with the battery or phone.
It's bound to happen a lot of people are buying these so not every phone is going to work as it should.

I agree completely that there is a battery issue. I've had a LOT of exposure to testing battery life, troubleshooting what impacts battery, etc... and I'm fairly confident there is some sort of battery issue. There are FAR too many people reporting stellar results for me not to as well. Even with how much I use use it, there was someone getting 40+ hours on battery... so I should be able to get 12 right after a factory reset... you'd think

Would love to know what his is. -92 isn't terrible but it's not great. You'd be amazed based on tower placement what even 50 feet can do, much less building materials, etc.
not saying this is for sure it, but i've been in this same situation with another carrier, was dead set it was the phone/battery and so were they, we tried 3 replacements before I gave up and determined it had to be a signal problem. Switched carriers and got the same exact phone, issue was gone.

Mine is exceptionally good. I get 0 to 1% drain overnight. My battery seems to last forever in the day. I don't think it's your signal. I have been in bad signal areas for long periods of time with this phone and no significant drain. I would definitely get a replacement and go from there. Good luck

That's what I thought... I felt like with all the positive reviews going on about it and knowing how to minimize battery drain that I couldn't squeeze any decent results out of it...

Absolutely. I have most crapware disabled and all apps hibernated on screen off but this is without a doubt the best battery stats I have ever had on a stock phone.

I had battery drain on my S7 Edge
cos i had Sync from old S6 Edge all the apps
I fresh install each App & that did help
No Issue on my S8+ till now :fingers-crossed:
Chk my Video in Signature

I had this problem, turned off location and always on display before heading to sleep, battery was at 96%. 9 hours later when I woke up, 93%. Before when I had both settings on, my phone dropped by 14 percent overnight. SOT is amazing so far, 2h 40 min at 74%. Will post pics when battery is almost dead.
P.S. - Compared to my Nexus 6 battery, I used to get 3 hours SOT before dying, looking good so far.

I went to the AT&T store and they hooked my phone up to a diagnostic machine and it said the charging system was defective. So new phone and fingers crossed.

That sounds to me like a bad battery. I get about 2.5 days now which is unheard of on my V20.

You got a rogue app my friend. My battery is phenomenal even with terrible Sprint signal in my area

Wasn't a rogue app, not after a factory reset. However the AT&T store validated there was a battery issue based on whatever test they used. Would like to get my hands on that testing app.....
