Piss poor battery life?

I don't know what I did to this phone but my battery life has been awful. I'll admit I'm a bit of a flashoholic, but I have calmed down.
I just installed CM9 alpha 3 last night. From 8am (when I left home) I did nothing but listen to music, with some very light browsing on the train. Music for about an hour and a half, browsing barely 10 minutes on 3g. I get to class and do a fair amount of texting. Fair amount being that's basically all I did in the class. Though that was on Facebook messenger app, on wifi. About a half hour later I realize my battery is about halfway. I look at my battery, it's at 29% with about 3 hours use. I restart the phone a while later (did triangle away and rebooted to test) and I got the battery critical notification.
Now this isn't new, or exclusive to cm9. A month ago in fact, I had miui (ics) for about a week, until I noticed by the time I get to class (after hour and a half of music) my battery was already at 60% and draining. Battery is also meh on gb roms (even calkulins) even with recalibrating battery.
Is my battery just ****ed?

No, ICS battery life is crap in my experience as well thus far. I am back to gingerbread until further notice.
You can try wiping battery stats and doing a calibration by recharging with the phone powered off, taking the battery out 5 mins, then charging it till full again (still with the phone off) - some people say that helps
EDIT
"Meh" on gingerbread roms , can you be more specific? I get about 15 hours with heavy use... pushing 30 with light use on permanent wifi.
Check your battery to make sure it's 1800 milliamps instead of 1500 as well.

You should try calibrating your battery and cycling it.

Battery sucks on the ICS roms, even the leaked stock TW ICS builds.

Tried blazer 4.1 rom yet? I get amazing battery life and no tweaks needed to achieve 24+ hr cycles.

Battery is horrible on ICS roms, I can barely get 6 hours on a clean install, when all I'm doing is texting!! Sometimes I can literally see the percentage go down every minute.

im not sure, but whatever im doing differently has gotten me acceptable battery life
and this is with 4g turned on, 1hr of voice calls, dozens of texts and ~1 hour of video/music

I'd consider that good for ICS. I can get the numbers and on screen time on GB that your images show with a day on battery and still have 40 percent left.

Battery drain issue?

Hey guys,
so I recently purchased an International HTC One X and hsve loved it so far, but I think the battery is draining too fast.
On standby, it drained from 93% to 89-92% in 8 hrs which I suppose is good, but while using, it drops pretty quick. I wanna know how many hours or how much percentage does your battery decrease by while on standby or during use?
By the statistics I have provided, do u think there's anything wrong with my battery?
PS: I used the built in battery app, go to settings>power
Thanks, Id really appreciate it if u could help out since I'm worried if my newly expensively bought phone has something wrong with it or not, ill hit the thanks button

Battery drain
I'm currently on Leedroid' ROM and the behaviour is similar to what I had with the stock rom and looks like the folowing:
Data or WiFi on, autobrightness on, autosync off
Hangs a litle on 100% then dops abruptly from 98-97% to 80% in about 4-5 hrs with a screen time under 30'
from 70% to 30% however, the battery drain "magically" improves giving 6-8 hrs of standby including 2 hrs of screen time of which the most is used to browse the net via 3G.
At the moment my stats are: 13h 50' on baterry, 2h 15' screen time, 21% left
I got a steep drop from 31% to 21%, just as I was checking the stats for this message, but bare in mind this is the first run with Leedroid (flashed last evening) so I expect things to improve.
After 10-12 days on the stock rom I remember getting some 3-3.5 hrs of screen time within 16 - 18 hrs total before reaching 10%.
So i suggest, give the battery a little time to settle, then adjust your usage habits according to what you get (like turning autobrightness off, data off etc).
I for one am waiting for some stable kernel improvments regarding the tegra power mangement (sounds cool, have no idea what I'm talking about and I expect to get some 20-30% more screen time within the same time period (18-20hrs).

I've been running a few battery tests. Last night I wanted to totally burn out the battery so I used it down to about 5% and started a youtube movie streaming over wifi at full brightness. An hour later...... it finally died.
The companion core on this thing can really confuse you are testing standby time or music and video playback.
I want a mod for the phone where I can toggle it to use 1, 2, or 4 cores. To the OS, it looks like core0 is also the companion core.

Thanks

Thanks for the reply
so do you think there really is something wrong with my battery?
i read on a popular android website that they played a video on mx player in loops and it lasted for 6 hrs and 6 mins, which makes like 17 percent for every hour of viewing. I downloaded mx player, gonna watch a movie, and hope the battery drain is on par
The less battery doesnt bother me much, what does is that im worried that there MAY be something wrong with my battery, gonna try out for a day or 2, gonna see if my results can match urs, thanks
just hope theres nothing wrong with my battery
PS: i have everything stock, i unlocked bootloader, flash CWM5.8.x.x but returned to stock later.

So the browsing drained about 70% of the battery right? Suppose those 11 hours of sleep took even 10%, and u have 21% left, so u spent about 70% on the browsing right? Thanks

when you charge to 100% it drops down to 95% then charges back up to stop over charging, who ever it doesn't show you the % it just says 100% thats why you can lose ~5% in a few seconds when first taking it off charge.
yesterday i got 14 hours 9% left and had just a little over 4 hours screen time on leedroid 5.1.
playing games is a massive drain

Battery Fix
I had a pretty serious battery issue during my first couple days with the phone, where the battery drain was extremely fast and inconsistent, sometimes dropping 5% at a time and giving me maybe 8 hours of life total.
The issue was that the battery tracking in the phone was messed up. When you go to Settings>Power, the default setting for "Fast Boot" is on. This seems to mess up the way that battery drain is tracked. I fixed the issue by turning Fast Boot off, charging up the phone to 99% (it wouldn't reach 100, that's how bad it was messed up), then restarting it. Now, it works perfectly and easily gets me through the day with moderate/heavy usage; I watched a 30 min video streaming from youtube of wifi and lost only 7%.
The downside is now the phone takes 5 seconds longer to start up .

I did that, and streamed on youtube for 30 mins, lost like 9 percentage, is it good? or is there something with my battery?

All of your battery issue will be sorted out people..don't forget that One X is still running on GB kernel n so is transformer prime..Nvidia n HTC are working on the ICS kernel..n once they are out with it our HOX is gonna blow away everything in the Market in both performance n battery life :beer:

32%: Brightness on low, data off, battery saver on and...

... it says I have 4 hours left. Extrapolate that and it gives me 12 hours on a single charge.
I have a stock LG Quantum. Is my battery in need of changing or is this just the norm? (honest question)
Cause this noise is ridiculous.

I have no idea really. My Lumia gives me 22% and 2 hours left, for what it's worth. Unplugged it this morning at 7:30, medium (by my standards) usage.

Probobly a battery problem? Check with the store you bought it at, the warranty should cover the battery problem and they will hopefully send it in and give you a new battery. Just describe it well to them.
I'm using LG Optimus 7 (since April 2011), and got about 26h battery with 100% charge, medium brightness, a bright tile theme and Battery saver. I usually use alot of 3G and Wifi and it's holding atleast a whole day.
I sent it in once for a battery fix and an upgrade to mango (and before that, the battery held for like 19h).

Hope you updated with the battery-fix update for Lumia
22% should give you like 5 hours atleast..

When I had my Focus it would do great on battery for a month, then all the sudden it would drain fast like yours. A factory reset fixed it for a month, then it did it again. I have no idea why, just my experience.

I did update it, but I've been hammering the phone for a few hours this evening. I got 17% now and 2 hours left, I think it's kinda fair. The readings that the options give while you're using the phone are really worth nothing tho...

Sometime, you need to re-calibrate the battery...
But yeah, sometime, i don't even know if my phone display correct battery life or not..
For an Example, i turned on Battery Saver and left the phone screen off while listening to music on it.
2 hours later, the battery dropped only 2%.

Battery usage is hardly linear though

..3g conn off and battery saver on i got 3,5-4 days with calls and msg-s,
i think its battery defect.I got optimus 7 with same battery as you do..

Thanks for the replies guys.
I did a hard reset a while back and yeah, for like a week I was getting 30+ hours of a charge. Now it's ridiculous like I outlined. I really hope it's a battery thing, but part of me knows better?
Unfortunately, my phone's warranty is over. I'm considering one of those more powerful batteries. But it's not OEM stuff, may not be very good.

It depends how you use your phone really, and windows phone calculates the time from when you use it until it drains. I just got my Titan for only a week, installed Skype on it and literally drained for a mere 5hours and 40 minutes on wifi, although talk time states it is 11h 50 min on 2G and 6h 50min on 3G, not surprising it lasted 5h on wifi.
Then after charging, it showed that I only have 5 hours battery life remaining and time since last charged it less than 1 hour. This looked terrible so I did a hard reset and first and went back to 1 day and 15 hours. After a while of not using skype, it lasted about 2 days on regular use (sms, push email, foursquare). Used skype again and battery drained, now I had it with hard reset so I just charged it full and did not use skype on it. Few hours later, it went back to 1 day and (now) 12 hours.

From my experience on my almost 1 year old Samsung Focus,
1. the battery life prediction on Battery Saver is not very accurate.
2. turning on the battery saver will greatly enhance battery life as all background services, syncs and push notification services are turned off.
3. 3G uses a lot of battery.
4. 2G or EDGE will enhance battery life greatly.
5. Amoled displays consume a lot of battery especially with a white theme.

WP doesn't actually last long when browsing over WiFi, I hope this gets sorted either in Tango or Apollo...

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Samsung Galaxy Note 7 before depleting the battery.
Then, drop a comment if you have anything to add!

Got 6 hours sot on my first usage starting at 90%, wifi only - internet/youtube/light gaming
Not impressive but decent, not as terrible as I thought sd820 was going to be aside from it being hot

Could be better but with all of the battery saving features you get, I don't have any issues with how long the battery lasts with the screen on.

You can also change the resolution to FHD. It will increase the SOT and FPS while playing videogames Great new feature :good:

6 hours of heavy usage with LTE would be very impressive, S7E exynos can pull off 6-7 hours in that regard.
6 hours with wifi and light usage is pretty typical even for mid range phones, my 7 years old iphone can pull off similar results in airplane mode.

Mine clocked 8 hrs with wifi, you tube, moderate gaming and online music.

I've managed about 17hrs SOT on my Note 5 once*
*Attatched to a battery pack lol

Snapdragon model note 7. Had 6 hours 30 minutes of screen on time, 3 more hours of standby, WiFi, Bluetooth, WiFi calling, and AOD all active, location set to battery saving, none of the power saving features active, spent lots of time in Firefox and Facebook messenger, watched a full movie from SD card at 100% brightness, sketched in autodesk sketchbook with the s pen for maybe an hour, and I still have 35% remaining. Been at full bars of reception all day, though, so no drain from low signal. Either way, I'm impressed. Especially coming from my HTC one m9, haha. And the phone stayed pretty cool all day, especially compared to the m9.

Hi, I'm looking at around 5 hours of SOT.
I believe I am experiencing severe battery drain on my phone. My phone doesn't last a complete day without needing a recharge.
Here are some quick stats.
- My phone has been on for 6h20m. Screen on for 2h17mn. Battery left is 58%. Although, I've turned on MAX power saving mode for about 1 hour or two today to ensure that my phone can last throughout the day.
- I usually have screen brightness at 50% or lower.
- According to the device maintenance app, and depending on past usage I have enough juice for another 6h50mn. That would lead to screen time of about 4 to 5 hours.
- I'm using dark themes whenever possible to reduce screen battery consumption.
- I've played a game for about 10 to 20 minutes today
- I've noticed that when my screen is on, every couple of minutes (maybe 5 minutes at the most) my battery percentage will drop by 1%.
- I mainly use my phone for gReader (RSS Reader with dark theme modee), WhatsApp (with black wallpaper) and the Economist.
- The top 3 items that have consumed my battery so far are: Screen (33%), Android OS (21%), Andoroid System (16%)
- I'm using two SIMs on my phone
- Believed to be Exynos. Bought it from the Middle East
- Always on Dispaly has 4 clocks on at all times. Probably using more battery.
Am I a heavy user hence why my battery is running out quickly. Or are there certainly issues with the battery?
Thanks for your feedback

I feel as if I'm getting horrible battery life as well. Been hard to tell being that I have horrible signal at work, if it doesn't improve with real world usage this weekend I'm going to phone att for a replacement.

SOT is a useless measure on it's own, doesn't tell anything about the battery life. I doubt you can get 6h SOT and that your phone can last until the end of the day. Yesterday I got about 4h SOT and around 14h uptime before I plugged it in again. Can't say that I am unhappy with that.

5 hours of playing Deemo and have 14% remaining, probably going to refund it for a S7E with exynos instead or keep it and sell it before S8 launches
Wifi only, brightness was around 30% auto. Not a gpu intensive game at all so not as impressive as it sounds. I believe the S7E exynos did 5 hours of pokemon go with max brightness.

I'm getting great battery. Better than my Nexus 6P, which I didn't expect. Seemed to run hot day 2, not day 3. Not...sure why. Love the power options, normally I hate to touch power saving.

Quoting myself here. Day 4 with the phone, 4:10 SOT with 18 h of on-battery time. Battery went down to 4%. Just a normal use, few videos, lots of music played (Deezer and Pandora), about 30m of Pokemon Go, news, etc. Once again, not unhappy with the results. I would prefer if I have another 5-10% left to account for the unexpected. Otherwise, all good.

Terrible battery life.

Hi,
I have a note 7 and for the past couple days the battery has been abysmal. Averaging 3 hours of screen on time. Also, the phone constantly gets hot (especially outside) that it has to lower maximum brightness to keep the device from overheating. With the phone on standby, overnight with always on display OFF, I will drain 10% of the battery.
Do any other note 7 users get this? I even drained 5% typing this post.

Go into settings-->drvicr maintenance-->battery then app monitor to save power

I dont have this problem. Battery life is pretty solid for me. Getting more on screen time then my iphone 6s plus!

Same here, I'm at less than 2 hours SOT and at 32% left. That and keyboard lag issues have me kind of unimpressed so far. At least I have a 14 day return policy. I'll have to see how it lasts during this work week.

Sounds like faulty units. I'm at 6 and a half hours of screen on time and 35% battery life remaining, on a snapdragon model. No battery saving features active, WiFi, location services, Bluetooth, AOD, everything on. Even watched a movie at 100% brightness to see how it'd affect the battery life. Phone stayed pretty cool although out.

That's the opposite for me. My 6S Plus gets >5 hours of SOT, the note gets 3< hours.

I get around 5h sot time but i also have bluetooth on and a few other things. I'm pretty happy

Right now I am at 5h 46m SOT and have 16% battery left. Not fantastic like the moto z force, but much better than my S7e I dumped after a couple weeks because of the horrible android OS battery drain.

Hi,
I have a note 7 and for the past couple days the battery has been abysmal. Averaging 3 hours of screen on time. Also, the phone constantly gets hot (especially outside) that it has to lower maximum brightness to keep the device from overheating. With the phone on standby, overnight with always on display OFF, I will drain 10% of the battery.
Do any other note 7 users get this? I even drained 5% typing this post.

I was seeing this the first couple of days I had the phone. All of a sudden my phone is not getting hot and battery seems to be lasting much longer. ... ??????

Here's my battery life. I've had the phone since Thursday. It's close to what I got on my iPhone 6 Plus. This was with light gaming, Facebook, texting, Facebook Messenger, Reddit and Tapatalk. Not bad if you ask me. My brightness is on auto, I do use the iris scanner and the screen is in cinema mode.
PS: I'm on AT&T with the SD820.

Replace it sounds like a dud. I get 5 6 hours sot. I went 20 hours 30 minutes from a 100percent charge at 1am to having 23 percent left at 9pm. 5 hour sot. Another poster says he got 8 hours sot. By using the medium power save mode.

100 to 23% in 20hrs while the phone was into deep sleep? that sounds like a faulty unit

I get 10pc per hour. V similar to note 5. Not great but i am a heavy user running BT for my LG smartwatch and wifi all day as cell signal is poor at my office.

I actually have had much better battery life than my S7E. Its odd but I think the slight revision of Touch wiz fixed some things. I also put Facebook and Messenger to sleep because they are the absolute worst at battery consumption.
Its worth stating that in week one, the phone is still cache prioritizing, cleaning up its IOPS etc. Not worth measuring for a while. But I am skeptical because My S7E was great for a while too. Its the sammy curse. Eventually you just have to factory reset to get your phone back.

Sounds like you need to reset your phone and start again

Same here, I'm at less than 2 hours SOT and at 32% left. That and keyboard lag issues have me kind of unimpressed so far. At least I have a 14 day return policy. I'll have to see how it lasts during this work week.

I'm not having this issue at all. I navigated for 2+ hours with the screen at full brightness and didn't burn up that much battery. I wasn't tracking it but if things dont get better for you, I'd say try swapping it out for a new one. You might have a physical issue with your battery.
