Battery Auto Calibrate

ROMs that contain this mod. When flashing a new rom or kernel, what is the procedure to re cal the battery?
I believe people should post their usage times when stating the number of hours of battery life. I hardly use my phone on Sundays and I can get 21 hours plus. The only way to determine battery life is to state the usage in time for internet, games, call usage ect.

There is a great app in the market. i think its called battery calibration. just charge battery to when it says 100% and run app. there is also an option to run it when not at 100%.

21 hours on hardly any useage? That's pretty bad.
Today I watched 2 hours of video from the SD card, then streamed 90 minutes from Netflix over 3G, plus the occasional short (less than 5 minutes) phone call, frequent email checks, and some random texting, and I'm sitting at 57%.
On extremely light usage, I unplug at 7am, go through my work day without turning wi-fi off (I let it auto detect and connect to my home network), random texts, check Groupon, check email, short calls, and 30 minutes or so reading with the Kindle app... By 4:00 I'm usually at about 85%.

my battery drops like 17% (from 100 to 83) just playing an hour of music off the sd card(doing nothing else) if I watched 2 hours of video, an hour and a half of netflix plus other usage my battery would be much less than 57%

my work has terrible reception so im always roaming. i was wondering if it makes a difference when i calibrate my battery at work as opposed to on the weekend when im at home and i get much better battery life? does it matter?

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

Thanks, that's what I hope to achieve. I did a factory reset, will fully charge and see how it fares tomorrow. Btw, I don't play games on battery precisely because of the massive consumption.

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:

That's perfectly fine. Battery drain will never be perfectly consistent (perhaps your video had better graphics/resolution than mine did). Looks like your battery's OK now.

Jellybean Battery Life issue

So i'm running stock jellybean 4.1.1 OTA (yakju) however i've noticed battery life isn't great, charged phone overnight to 100% its been on standby for 7 hours and is already down to 68% screen time on is only 3 minutes, is this normal battery drain seems a bit excessive for standby.

depends on what you have running and syncing, etc.
you gave us no screenshots or anything to base anything off of.

I just charged up my phone from a 20 hour run, almost 4 hours screen time broswing with wifi mostly... stock JB 4.1.1
edit: oh i forgot i am using franco.Kernel

On my Nexus battery life isn't much better than on your Nexus, It is normal or then my Gnex battery is poor again..
I'm using "takju" JRCO03C with it's own radio + kernel so all is stock and battery life is enough good, for me on yakju builds the battery drains much much faster than on yakjuxw/takju builds..
My Galaxy Nexus's battery stays 14 hours with not using it and then battery is left something 12% or less, and when I use my Gnex then I can use it like 2 and half hours and then the battery has too less life to use it... (when Clock Alarm is on, and Hotmail + Facebook notification enabled...)

Google Now is said to use lots of power, have you tried disabling that?

I am also getting really bad battery life since JB. I have the extended 2000mah(?) battery so this might be the issue although I have not had any issue with ICS, I got about 26 hours with this battery on ICS. Now on JB I will go from 100% to 85% in 2 hours and all I did was text about 10 times, no phone calls. Today I woke up at 6am listened to Google music going to the beach, at the beach did not use the phone except to check the time.
Listened to Google Music on the way home, got home at 6:30pm battery was at 31%. I did not surf, made one phone call that lasted 30 seconds.
This has been about consistent since JB installation. Everything is stock except for the fact that I am rooted.
I am currently conditioning my battery, when done Im going to remove facebook and see what happens. Also can we "freeze" Google Now? This so I can test the batter.
Thanks for any suggestions and/or ideas.

I'll chime in to say I'm also getting slightly worse battery life on JB. I'm mostly observing idle battery drain during the work day. On ICS it was a steady 0.5%/hr, on JB it is over 1%/hr. So before I could get away with not charging it some nights and it'd only lose like 3% overnight, but now it's more like 7%. The phone is stationary during this time so I can't imagine Google Now is contributing much. I'm not rooted, completely stock.
What are some options available to investigate this? BetterBatteryStats or apps like that?

Galaxy Note 2 Battery Life

So I just got my Note 2 this week and I'm only getting about 9hrs of use before hiring 30%. I checked a bunch of reviews and they were saying they usually got a day in a half with moderate use. How about u guys? How long are u guys getting of of your phone? Are u rooted? Using a juice app? Is an SD card inserted? How long does it take for your battery to recharge?

Use search button before opening a new thread?

I have to charge it in between, but I am always on it. Still the best battery life I have gotten out of a phone since razr maxx.
Sent from my SGH-T889 using xda premium

I've been getting 1.5 to 2 days on mine with my normal usage.
I spent a few days at my in laws where I used it a solid 8 hours near continuously and ran it down to 15%.
I was in an area of no cell coverage and had wifi calling running all day.

16 hours yesterday with moderate to high usage. 40 minutes calls, 25 sms, 6 mms, 10 photos + retouching, 3 app updates, 1 install and a total of about 3-4 hours greader/browser reading. Wifi on, 3g on, power saving on and sync on. Display brightness between lowest and 50%. Display on time 48%. 19% battery remaining. Stock international version, unrooted. No LTE.
I have no idea how long it takes to charge. Sorry.
Trivia: The word "Nomofobi" (swedish) or "Nomophobia!?" (English) has been added to the Swedish dictiodary. It is the fear of running out of juice on your mobile phone!
My nomophobia disappeared with the purchase of my Note II.
I hope you sort your battery issues out.

Question, those with insane battery life, are you rooted? The first day I got the phone, it had 16 hours before going down to 5% battery life, and I had about 6 hours of screen time. I wasn't rooted.
I rooted yesterday, and the battery life today was about 12 hours, and its at about 20% battery life.
I was curious, maybe rooting the phone has a parasitic effect on the battery. All I did was remove T-Mobile's bloat ware, nothing else.

I don't see any difference in battery life pre-rooting and post-rooting. I consistently average around 16-20 hrs depending on usage. Typical day use for me is to take it off the charger at 6 am, then I usually have 1 to 2 hrs streaming on 3g, another 2 hrs streaming on wifi - all using Plex. Youtube about 1 hr, maybe 1-3 calls lasting 5 mins avg., 1 hr playing games, and about 1-2 hrs browsing internet. I'm not a heavy texter or gmail, since usually I can do that on my laptop at work.
I usually don't put the phone back on the charger until around 12 or 1 am, with about 14% left. I usually have wifi on, gps on, sync on, brightness level around 10-20% except outdoors (then it's full brightness), power saving mode on, and screen time out at 1 minute.

I had realized that I had the brightness set to full brightness since early in the morning lol. All in all, I don't know any phone that would last all day with full brightness and doing all I did.

Battery usage

My battery stats have improved greatly by turning off location completely.
Took it off charge at 6am and with heavy usage
YouTube internet calls etc
still have 65% 16.5 hrs later.:good:

Just starting to play with battery use on my new G5. 100% charged 10 hours ago just before bed.
On a day to day basis i am a pretty light user. Calls and texts mainly.
Left phone unpluggged so it slept and 7 1/2 hours layer its at 93%.
20 mins music and email checking 19 hours in its at 88%.
Have Greenified much in the way of apps which i think improved things. Compared to the Sony i had the G5 seems to have ok battery life.
Its certainly in the useful, full day and better range.

Is yours rooted? I tend to get 5+ hours screen on time sometimes 7 which is amazing for a phone this cheap.

Same here, I have about 4-5 hours of screen on time with greenify, non-rooted. I'm a regular user, messenger, emailing, browsing, spotify etc. I'm also using Adguard which has its impact on the battery but a small price compared to having ads all over the place

Nope, no root as yet. And actually i may not depending on what ROMS become available in the future. Pretty happy with the way this is setting up and Android 7.0 stock. I think i may well leave it unrooted until after Android O hits and see where i go from there.

i'm rooted and the battery is very good, i got 7,5 hours SOT, usually i have 5-6 H of calls and 3H of SOT, 2 sims active, wifi and 4g always on, and the battery is 20-25% when i put on charging from evening to the morning. Very happy with this battery

Very good battery for price of the handset

I don´t know it´s a isolated case, but since i bought the phone, the battery is pretty bad, yesterday i tried to charge with another power adapter and my battery it´s lasting longer, anyone have this same problem?

Sometimes this happens to me.
When i keep my phone overnight(Battery Saver ON) even wid a charge of 60-70%, next day mrng, the battery is completely drained and phone is OFF. This doesnt happen daily, happens only sometimes. Any guesses why dis happens?
