When did your battery life start to get better?

I have had the phone for 5 days and with fairly light usage, I am still not getting good battery life. I turn off all data and wifi when not using it and screen on time is below 2 hours.
Below is a screenshot of my battery life.

It doesn't get better...get used to it until its fixed in an update , along with the other big issues.

By about the 3rd day it seemed better. But it's also difficult to gauge because the first few days you're bound to toy with it constantly.
Until there is an empirical way to gauge usage, like an amp meter attached to the phone - it's all perception imo.

In the top left you have three things running in the background, im assuming constantly. Uninstall them, especially the battery percentage since you can look that up easily on your phone

Do yourself a favor and try aokp milestone 1 from rootzwiki , and also download lean kernel 1.1.1 on xda. Use interactiveX governor for kernel. This is the exact setup I am using now, and have been for a few days and have been getting insane battery life. Hope everything works for you.

Last time I checked lithium ion batteries don't get better after a few days and yes there are software fixes for battery life and bugs..

You really have no idea what you're talking about. First of all, it will get better, I won't bother explaining the science behind it considering you can do your own research, but it will, also, it can't be "fixed." Just like they can't make it an 8 mega pixel camera in an OTA. You can get it much better by doing custom roms and thigns of that nature.

It got better when I turned off vzw backup and google +.

Best I got is 16 hours bone stock just an extended battery. Worst I got was 4 hours(screen was on the whole time) watched 2 movies before I plugged in. I average around 12 hours from 100% to 20%.

First off, it's hard to tell by your screenshot how good or bad your battery life is. You're burning approximately 10%/hr, but maybe you had your screen on or were surfing the internet for a portion of that time. Anything that involves data transfer will kill your battery faster.
I got my Galaxy Nexus on Wednesday, and I've had great battery from the start. I calibrated it by letting the phone's initial charge die down to zero, and then charged it all the way up to 100%, and then used the Battery Calibration tool. I drain between 2-3% hour with light use, but can obviously drain much more depending on what I'm using the phone for.
That being said, for those on this board who think an OS upgrade is going to fix the problem, I highly doubt it. I have a reasonably poor cell signal (averages around -95 dbm), but still get solid battery life. Given that we were all issued phones with the same software, if you're experiencing incredibly bad battery life, I'm going to point my finger at the hardware. It just doesn't make sense that some of us with 4.0.2 get great battery life, and others do not. You probably have either a bad battery or a bad phone. Now, I'll probably get called out for saying this, but watch all the posts that follow when the update releases, when people still have poor battery life.
This is my 3rd Android phone (Incredible, Charge, GN), and every one of these phones has had poor battery life. On average, if I'm playing around with the screen on, I'm draining upwards of 10%/hr, if not more. But if you properly calibrate the battery - which is VERY important - you should easily be able to get a full day's charge out of your phone.
There is a post on XDA about the 13 steps to proper battery calibration. Once I followed it on my last phone, my battery life went up at least 50%. You have to let the battery drain to 100%, then bump charge a number of times, then use the battery calibrator.

Try running without JuiceDefender. Constantly toggling data on and off (or wifi on and off) actually hurts battery in almost all cases.

Your results may vary, but when I used Juice Defender or Green Power on my Droid Charge, I nearly doubled the battery life. I haven't put it on my GN yet because my battery life is much better than what I had with the Charge.

No using JD or anything like that. Just the the phone do its thing. I don't even open the multitask button unless I want to switch between apps.

Gotta be a software issue with the battery.
Just this past weekend in Wash DC. Very strong 4 G market.
I had it fully charged off charger. After 7 hours without touching the phone even with google plus sign out, the battery went from 100% to 54%. It's like the phone was active a lot without me even touching it. No SMS/mms either. No emails either.
Know. I did same thing and put it on airplane mode with it 100% charged. After 7 hours on airplane mode it was at 98%.
So it's gotta be an operating system issue.
I tried it on wifi instead of 4G mode. And battery drainage was down to 72% after no use overnight.

Best thing I have found is to totally drain battery to the point it the phone will only slightly vibrate. Remove the Battery. Put the battery back in and then fully charge with the phone on charge mode to 100 percent. Unplug. Then plug back in a few seconds later for fully charged to reappear. Done. Really helps to do this once every month or two. Credit to someone on another forum for this tip. Turning off data when not in use and low screen brightness will substantially increase battery life. No syncing, bluetooth or wifi will help. An app called GSam battery monitor will identify apps that suck battery. I use longevity by trend micro to shut my data off.

Fully draining a lithium ion battery will significantly decrease it's lifespan. Any positive effects you see from this are probably not measurable, or scientifically reproducible. Your other tip is solid, disabling data (or using an app to do so) greatly increases battery life. As well as turning down the brightness.

Had no idea this practice decreases lifespan of the battery. Good to know. I thought the this resets the phone ability to recharge the battery to the fullest. That's what I thought. I seem to be getting some benefit.

Battery lifespan for lithium ion batteries is measured on how many cycles its been through (hits 100%). If you go from 90% to 100%, you just used up a battery cycle. Even 99% to 100% counts as a cycle.
The method you described in your earlier post is for conditioning your battery, it works on older batteries but is not needed for lithium or poly lithimer batteries.
Tips for battery life, disable radios and keep screen dim. A dark wallpaper helps too, white screens are a battery drainer!
Sent from my SAMSUNG-SGH-T989 using xda app-developers app

Get a app that disables other apps that start up on system boot-up or other events. Autostarts its a good app I use. As you all should know dont use app-killers unless u know how and when to use them (READ). Like said keep ur screen dim or on auto if u have that issue like me were ur constantly going in n out at work and find ur phone too dim for daylight. The darker your themes the better battery life. Remember that ur screen is one of the top (if not the top) battery drainers. Data, wifi, gps, bluetooth, auto-sync, running widgets, live wallpapers...if you dont need it on or could live without it, then either turn it off or get rid of it.
Also like said before, lithium-ion batteries dont suffer from memory effect like older rechargable batteries. If you could avoid it, dont run ur battery all the way down. Be free to charge ur battery as often as possible and that way you extend the life of ur battery.

Use the lowested sync frequency setting you can or manally sync. Wifi tether guzzles juice. Live wallpaper is a killer. Make task killing a subconscious reflex. The smaller the number is next to "running in background" also makes for more time away from an outlet. Of course these may not help any one else, but it works for me

I run the ParanoidAndroid 2.51 rom (10/24) with the KKO kernel and it goes pretty good so far. It may be the first day of using it but I will expectedly average 20hours of use on it. (using the live wallpaper phase beam the whole time). Used the wheatly governor with SIO and changed the max cpu to about 1028 so its only using 1Ghz. (seem to get decent battery life)

[Q] What is the best way to test battery life?

Hello
I've downloaded a new rom & i want to know if the battery life whether good or normal, what is the best way to test it?
Is it simply by calculating the amount of % loss per minute?
Or fully draining battery twice & then getting overall time consumption till depletion?
Your cooperation is appreciated
Sent from my GT-N7100 using Tapatalk 2

For me the best way is just using the phone as I normally do for a couple of days.
If the battery runs flat faster than usual then change roms.
If not, I stay lol.
I figure that calculating % per min will only be useful if yoi can replicate the same conditions each time.

Is my battery going bad?

I've been noticing that my battery life seems to be decreasing consistantly. I've tried recalibrating my battery stats a couple of times, but it didn't seem to make a difference.
My usual charging behavior is to let the battery get down to 15-30% and the other charge it either overnight or all afternoon at work, depending on when the battery gets low. I try to either keep the phone on the charger as long as possible or let it get as low as possible so that I'm not running additional charging cycles through the battery. The screen is usually set at 35-50% and it is always the thing that eats up most of my battery.
Am I imagining things, or is my battery life nowhere near what it should be?

Which ROM are you on? LL7 users have reported weird battery issues. Even I had very bad battery life on Indian LL7, had to factory wipe data and cache for the battery to function decently. Am on Indian MA6 now and the battery is superb.

I'm on JellyBomb 12.1, LJC base. I don't think it's a ROM issue, though, since the Android system never eats much of my battery. The culprit is always the screen.

[Q] strange battery drain (updated)

I'm not complaining about battery life bit I just fond this strange how with nothing running my phone went from 20% to dead that fast. Phone was locked and in my pocket. Anyone have any ideas? It's also not the first time this has happened either just the first time I thought to get a screen shot of battery usage right after
**Update**
Now my phone is dying at random :/ it does it from 50%, 30% etc. Any suggestions (i.e. battery calibration, full factory reset) or should I make it stock again and get a replacement?

Batteries are gauged by how much voltage they are pushing in most tests. Though from my hobbies of electric rc cars, I've learned that batteries can change their voltages simply from a temperature change. While these changes may not be significant, they do represent differences and used to play a big part in my fifteen minutes charge cycles. It's harder to receive a positive rating in a cell that is low on power than it is with one on max charge. So if I'm down to twenty percent or so, I use my phone very sparingly. Has been pretty trustworthy for me over the years.
Either way, suspicious battery drain is usually a rogue application sitting there eating resources as the phones we use do seem to monitor battery life pretty good compared to the old voltage meter methods.

I found the htc-Facebook app drains funny on the battery. When I loaded bonestock, then loaded Facebook from the play store, it helped my battery. I think it's the way the htc-Facebook interacts with blinkfeed.
Could be completely of base, but I know the htc loaded Facebook is slightly different.

I assume you had a good signal everywhere you went? Nothing drains a battery faster than being in an area where there is very low or no signal. It constantly tries to connect and it will KILL your levels very fast. I see this quite a bit in my work place. Employees with Sprint and many times AT&T will complain about their battery dying at work only to find out the phone was constantly searching for a signal.

You know, I totally forgot about that. I used to have that issue with Sprint myself. Killing the data would eliminate TONS of battery usage when I was at work. Now that I'm on Verizon, there's never much problem. But he's completely right. If you're not getting a quality signal your phone may be searching and that can be an all day thing which just eats a battery alive.

I am in a near perfect signal. I'm pretty sure its has nothing to do with coverage. What's strange to me is the phone immediately dies. It will be at 50% and then the screen goes black and won't come back on. Once I plug it in the phone finally comes back on and is at zero.

I'd have to search around, but taking these batteries all the way down actually reduces their effective life.
Sent from my DROID2 using xda app-developers app

Basically, the more you drain the power before charging, the less charge cycles the battery will have. Someone who charges at 75% compared to someone who charges at 25% will have more cycles over the life of the battery. I can't remember the exact numbers, but there's been plenty of studies on the issue. And if I'm correct charging at those numbers, the 75% will have more than twice the charge cycles over the life of the battery. The biggest battery killers though are actually higher amperage charges. One study showed more than five times the life cycle at 3.7v per cell compared to 4.3v. And the charging required to power the higher voltages actually cause more damage over time than the extra mah output is worth. The HTC one has a decent setup and the stock charger doesn't over feed the cells. But in not sure if it will make it to the 700 charge cycle that a two year contract may leave a user with.
