[Q] Batt life

Am I the only one who doesn't get 4 hours of screen time from a charge? I've seen many posts about it, and I average about 2. This is on aosp/touchwiz and many different kernel combos.

I don't typically get 4. I get about 3 or less. And I don't overclock like most do. It all depends on what you use your phone for , how good your service is, phone calls/ texting you do. I listen to music every day which hurts my amount of screen time, and I don't get very good service most of the day, which also hurts it. I have noticed that installing JuiceDefender dramatically helps so my battery drains much slower when I'm not on it by turning off wifi/4g after a few seconds, and back on at intervals to sync. CPU Sleeper is also a noticeable gain after you install it. It shuts off the extra core or something when you don't need it.

On a regular basis, I've only gotten around 2-3 hours of screen time from a full charge.
I've used stock, CleanROM, and SynergyROM
All the same.

There are SO many variables that can contribute to lower battery life. Screen brightness, constant device wakes, account sync, application efficiency, etc. I normally get 3 hours of screen time because I keep my sceeen at half brightness and I wake my device up a lot throughout the day. I'm willing to bet I would get 4 hours if I reduced the amount of device wakes. But who knows.

Yeah I understand wake locks and such I just thought I was getting abnormal battery life. Maybe not. I only lost 10% after sleeping in for 12 hours. Medical classes haha. But my screen time seemed low. Oh well, I carry a charger everywhere

im in the middle of demonstrating this and making a post about it. Battery life is dependent on user and the phone. Nobody will get the same battery life.
im on the stock size battery and im at around 1 day 4 hrs of battery .... 3+ hrs of screen time...and i still have 39% left.

Like I said I realize that it varies by user, was mainly trying to determine if I had a bad battery. I had seen many people post about 3-4 hours but hardly any about 2 hours

Why do Android battery life suck?

So far, I've owned 3 Android phone, and all of their battery sucked. I owned an Evo 4g, HTC Rezound, and I had 2 Galaxy S3's. Even with Extened battery, the battery won't last as long as an iPhone. And it doesn't stop here. It takes FOREVER to fully charge the battery only to find out that it gets depleted super fast. On the S3, I would be at 20% at the end of the school day, but with an iPhone, I end up around 60% with the same amount of use. The phones go up 1% after 5 minutes when plugged into a computer, and its annoying. I love Android with all my heart, but I can't deal with this problem. Anyone know of phone that has really good battery life (besides the MAXX)?

An iPhone's battery life is roughly the same in each iteration as a device from the Galaxy series. In fact it's been tested and the Galaxy S III lasted 6 hours and 55 minutes compared to the iPhone 5 which lasted 7 hours and 13 minutes. Both OS's implement battery management very well, and at the end of the day battery life is mainly dependent on user use. You can't expect an Android device to have numerous data hogging widgets as well as numerous background processes active, all while surfing the web with multiple windows open, and not drain just a little quicker than an iOS device that doesn't even utilize true multitasking. Please.
Also: It doesn't last as long as an iPhone "even with an extended battery?" GTFOH. Either your iPhone runs on nuclear material or you're full of sh**.

Why don't you use something like BetterBatteryStats and find out why the battery is being used ?
I get 3-4 hours of screen on time on my S3 with stock battery and kernel, but with some minimal battery-saving settings.
It used to be a lot worse - but I actually investigated and found out what was eating up the battery. I guess I could have just complained about it, but it was a lot faster to just work on finding a solution. I've been really impressed with how long my battery has been lasting lately - and it didn't take all that long to just read the BBS report and make changes.

In my words, its actually depend on your uses. Now a days we have 4"- 5" screen, where lots of processes are running in background. Using Dual Led Flash light for camera & having lots of Games,applications & files. We were used to have phone like NOKIA & BB. Where we just clicked over a button & thats all. But now when You click on screen, whole screen has to be work.
But yes, Few companies has taken it hard & Provided battery like MOTO MAXX.. also few have kernel bugs. So, it totally depend on you buddy, how you take it. Use data connectivity less & check whether your phone is going to Deep sleep / other name as per phone is going or not.

Be realistic with the brightness, keep it on auto don't run it at 100%. Try different ROMs with tweaks. Adjust settings with kernels for a faster battery recharge. Your options are infinte. Maybe android isn't for you.

I had 2 extended batteries on both the S3 and the max screen on time I ever got was 3 hours.
And still, there's the problem of charging. It just takes too long!

There's an official Google statement that wiping batterie stats won't improve your battery life.
Wiping the stats forces android to recalibrate and calculate the battery stats.

Do you mean the time for one or both batteries ?
I get 3-4 on stock battery - but I always have my screen on the lowest brightness - and sometimes lower (using the Screen Filter app). I'm inside most of the time, so I don't need a very bright screen.
The only time I really lose battery like crazy is if I'm playing Ingress - because then I need to turn the brightness up and GPS is constantly updating so it's not exactly unexpected.

I never seem to have issues with my galaxy s3. You might want to get a battery management ap to see where all your battery is going towards. Or you might just be a heavy phone user and in that case, it wouldn't be the phone's issue...

My battery life increased 10 fold after jailbaking my phone...

I get 4 hours screen on time with average use
Total on-time varies with what I do. Could be 10 hours could be over 24
I'm usually listening to music, texting, playing the DS emulator, browsing, or just social media
Sent from my Nexus 5 using xda app-developers app

so anyone ever reached the phone from fully charged with standard SOT 3-4 hours from your nexus 5 and the battery still runs good ?

For me the key about the N5 battery life is two fold;
1. It loses very little juice on idle, even with all of the radios on.
2. It charges exceptionally fast.
Now, if you run screen brightness up and use google navigation the battery can go fast. Real fast. But for me, what is important is that if I know I am going to be away from the charger for a while I can easily tweak my behavior to get me there.

Expected SOT

Hi,
recently I bought N5 and I am very pleased with it. I could say that I love it. But I am worried about my battery. When I was buying it, the dealer at my carrier store, was hiding the box when opening it from me. I think that the box was not sealed any more ( i dont know if it is only in my country but here it's usuall that when buying a new phone they cut the sticker on the box infront of you). When I called at my store they said that they had only one more. And I am worried that the phone was used befor me for showcasing in the store. My battery usually lasts for two days ( I also have N7 so when on university i use N7 for heavy work) but barely get 3 hours of SOT. Wifi and 4G mostly off and brightness at minimum or max at 30% if on sun. Assistant of, gps of, ART on, using snapdragon BatteryGuru. I would really like to know what SOT should I get with this settings. And if you guys think I should go for warranty and hope that they replace my battery. Is there any way of seeing if the phone was already factory reset? Also I saw guys getting 5-6 hours SOT with wifi on here on XDA. Don't get me wrong I love the standby time but when using it (FB, twitter, messaging, browsing Chrome, 2 mail syncing) the battery drains like F1 car drains gas. If this is somewhere answered close the thread and point me there . Thank you

screen on time is totally dependent on personal usage.
the best thing to do would be to root it and install 'better battery stats'. then you can analyze your battery properly. feel free to let this run for a full discharge and then post your screenshots

Yeah the problem with SOT is purely personal and that is why I posted here to see what you guys think. But still it is interesting to see how different the time can be from user to user. Will post screenshots in the evening.

remove this. It doesn't help and if anything, it makes it worse

The battery drains whether the screen is on or off. If you're getting two days of use with 3 hours sot I would say that's ok. You might get 5 hours if you drained the battery in a day. Does that make sense? It does in my head!
Sent from my Nexus 5

Ok so I removed Battery guru. And here are my stats from today (this was not my normal day of using it). Through the day the screen was almost constantly at the same level of brightness. And a lot of wifi and even 4g usage. But my battery could be draining a bit faster too because of not that good cellular coverage.
As pepdavies said with my normal use probably I would get closer to 4 hours if I would draind a battery in a day. .
Can I aske one more question? If I charge my phone over night and phone is off, will it overcharge my battery the same way as it would if it was on?

ive always charged my android devices overnight while they are on, nothing bad comes from it. you will be fine. i do it on my nexus 5 every night, yet still see at least 5 hours sot every battery cycle(5+ hours sot because i use lte exclusively, it gives better battery life than 3g/2g).

You can leave the phone plugged in 24/7/365, on or off, and it will never overcharge, whatever that may mean. Nor will it overheat, slow down, melt, or explode.

I got 7 hours of screen on time by having the screen on a low brightness but that is only practical in a dark environment. I've also disabled a lot of google stuff and uninstalled google+ which was destroying 20% of the battery regularly. Generally 5 hours of screen on time using lux to lower brightness levels but to a point where the screen still looks nice

4 hours sot is typical for stock

i dont really see how anyone can enjoy using there phone at minimum brightness unless its in a dark room i keep mine at 25% and it looks damn good using a tweaked gamma profile. Regarding battery i average 4.30 hours screen on time and 23 hours total with wifi only mostly web browsing and as said already there will be no harm in charging your phone overnight when i wake up its at 100% and battery temp is at around 24c

you are right that it will never overcharge, it is not optimal to keep your device with a full charge of battery for an extended period of time. by extended period of time i mean 5+ days

there are many people in this world and we all have our own likes and dislikes.
when im outside I enjoy being outside and do not use my device except to check a notification or two. so when im inside and in an average lit room, I can drop the brightness to about 15% and that is enough for me. remember, lighting the screen is the phone's biggest battery hog. any decrease to this will increase your SoT. I enjoy getting an extra 2 hours out of my device before i have to be tied to a power cord
that said, im waiting for my zerolemon battery case to ship and can't wait

Holy Battery...

I have never had a battery be this good. Rooted with Greenify. Running Skyfall.

Kinda ridiculous. 16 hours and 60% full over here on just regular power save mode....SkyFall also

Yeah this phone gets way better battery life than my s4 did with same size battery. Love it. Does greenify really work that well? I have never used it as I have great battery life without it.

Lots of reviewers are talking about how the M8's battery lasted longer than the S5 too. Samsung needs to stop slacking on the software and give us a lightweight touchwiz. I absolutely love Sense 6 and I'm usually an AOSP guy. I'll probably try out GPE Roms once they're stable but honestly the new sense is everything I want out of android software. Minimal, clean, customizable, smooth and fast.

Don't get me wrong, I'm getting great battery life as well (though coming from a VZW GNex, anything would be an improvement). However...posting screenshots of how long your device has been off the charger with no other information (screen on time, app battery use) doesn't tell us anything.
Hell, I could leave my phone at home on wifi with the screen off and not touch it for the next 3 days, take a screenshot of any remaining battery life, and post it being like "OMG I got 3 days of battery life, this is amazing!" And it would be just about as informative and truthful as your screenshots (not including yours Evocm7, obviously).

sorry im kind of a noob i am aware of greenify i have used it but whats skyfall? I tried searching but nothing is coming up but james bond.

I hear what you're saying. Personally, I'm not trying to participate in any scientific study on the matter. All I know, and all I care, is that I've had the phone off charge for 29 hours now... using it the way I normally use it during an average day ( pretty light)... and I'm still at 40% battery.
Coming from a malfunctioning POS Droid Charge this phone is a godsend. I used to have to carry an extra battery just to get through an 8 hour shift at work starting on a full charge.

lol I came from a GNex, so we're probably in the same boat. Even on wifi with extremely minimal use (10-15m screen time all day, which with how slow and laggy it was I didn't really care)), I would be down into the 60%'s by bedtime. If I went to the gym with full battery, after listening to Pandora while doing weights, and watching Netflix during cardio, it would be into 20-30% by the time I left, total of maybe 1 1/2 - 2 hours.
I flashed Skyfall the other day after charging my phone to full, and by the time I was done flashing, re-installing everything from TiBu, updating a few out-of date apps, and setting everything up, it was down to maybe 95%. And that was with the screen on for probably 20 minutes straight.

I think taking into consideration the snapdragon 801 chip how it saves battery, sense 6 being light weight, if one needs to you have the choices of battery save mode and if that's not enough extreme battery save mode! This phone came built up from the floor up. Now if we just had the 1.56 software version with all the above included stock and operating correctly, I'm sure we would see even more battery savings!

There are very few "de facto standards" for anything in the Android ecosystem...which is why we like it. I use a combination of GSAM Battery Monitor with the root companion, and Wakelock Detector.

Dont get me wrong, I get decent battery life, but nothing like you guys. For those of you with amazing OST are you guys using Google Now? I just installed wake lock detector to see what is causing my batt to drain more than others.
