[Q] Odd Battery Charge Curve

hi all,
i noticed the charge curve on my evo is not linear. at first it's logarithmic and then linear (see pic). everything is off (3g/4g, wifi, bluetooth, sync) while charging (only turning on once in a while to check the %). is this normal?
ive wiped my battery stats and done all that. during use, the battery drops to 60% quickly and then discharges slower. im using deck's gb 1.3 rom, havent changed the kernel, no wake lock issues as far as i can tell.

I was having the same exact issue. I bought a new battery and figured it must be bad when it would jump from 80 percent to full in a matter of minutes. Then it would discharge to around 70 percent in a matter of an hour. After it hit 70 percent it would discharge more slowly. This was a battery that the Sprint store gave me and I was led to believe it was new. After it did this weird charging discharging issue I went back to sprint and this time received a brand new battery in the package. The young lady behind the counter showed me a box full of all types of used batteries and explained they probably pulled one out of the box of the used batteries. I exchanged my original battery because it wasn't fully charging anymore but the weird charging spike I got with the replacement battery was a first for me. Anyway the "NEW" battery is working like it should so you may be looking at a bad battery.

I know you said you wiped battery stats but did you calibrate the battery at all?

oop. forgot all about this post. thanks for your responses.
i assumed something weird may have happened from my going stock to root so i checked out a friends battery. he never rooted his phone. unfortunately i get the same charge curve.
yes, i have calibrated my battery/ ie, charge to full, wipe stats, then drain phone til shut off.
i will try contacting sprint/htc for a new battery and see how that goes.
anyone else have this issue?

Me, all the time. Have yet to have a different curve ever. Mine happens a little higher though, around 70%. Try battery monitor widget and you can see the actual charging voltage

After you drain the battery completely, charge it to 100% without unplugging. Recalibrate with that method and see if it helps.

Best battery for DHD?

Hi there.
In currently running stock battery and struggle to get like 7 hours moderate use
What's the best battery on the market in the Uk which isn't too expensive
Cheers

The stock battery is the best out there. The other ones who claim to have more mah are just fake mah's.
You just can't put more mah's in the same size!
How old is your battery?, I bought a new one last week and I am now on 8 hours, with 58% juice left!
I'm using Redemption v1.0-Alpha, but also had VQ RC3.

I've had it for about 5 months bought as refurb and battery has been crap since arrived 1 hour music drains 20% and when screens on 1/2 brightness it's 1% per 30 seconds worst I've had it do was tethering and battery went from 100 to 0 in an hour playing games is about hours

Hmm, what drains most juice from your battery?
And did you have this also on stock rom?
This is my status now:

Screen which is at 75%-80% usage even at 1/2 brightness
But its the fact that to get any performance on battery life at all out of my phone i have to not use it which is what I don't like about it or i have to have a realy dim screen.
Quick browsing of Facebook and tapatalk can easily drain 10%
Yes I did have it on stock rom but ICS has improved it a tiny bit

Have you tried to reflash the rom?
That may help sometimes. And otherwise try another rom, RC3 gave problems with me so now i use Redemption, works very smooth.

Yeah I have
I might try the calibration trick where you:
Turn your phone on and charge it for 8 hours or more
Unplug the charger
Turn your phone off and charge it for one hour
Unplug the charger
Turn on the phone and wait 2 minutes
Turn your phone off and charge it for one hour
Unplug, turn it on and use as normal. Your battery life should now be a lot better
See if it helps
if not I might try a few different roms
Cheers the replys

I have tried that also, and also whiped my battery stats with my old battery. But it never helped me.
Let us know if it helped you!

Will do
people are reporting that battery pulls at every turn off seem to help
How much do you actually use your phone to get 9 hours at 50% (display on time)?

It doesn't helps you to pulln the battery out. After restart you see about 5/10% more battery, but in a couple of minutes its at the same level before the pull
Well that was not with much use. Mostly on WIFI and sometimes 3g on. Some browsing and twitter/facebook.
Today i had left 3g all time on and used my phone as I alsways do.
Keep in mind this battery is new and has only be fully charged 3 times, so it doesn't have his full capacity.
See attached foto's!

Been on stock battery and ROM for the first year of my DHD, battery life was absolutely horrible.
By the time I got into running custom roms my stock battery no longer held a very good charge. I picked up a couple Andida batteries, they say they are rated for 1800mAh but after running some tests they are just about the same as a new stock battery.
Been running on them for a few months now and I get just over a full day with my usage habits.

Has the battery life decreased since you first got them? Or do you get the same result as in the beginning?

There's an app called battery calibration in the google play. It shud help with ur battery life problem, it calibrates the battery after every flash of a new rom
---------- Post added at 08:36 PM ---------- Previous post was at 07:59 PM ----------
roms also can have a negative impact on battery so make sure that that isnt ur problem

No need fot that app. You can wipe the battery stats with EXT4/ CWM.

[Q] Extended Battery not working at all?

Hey guys,
Ive been trying to diagnose this problem for a while, still cant figure it out. I get TERRIBLE battery life, for having a 3900mah battery. Im really really confused what is going on. Its a VZW galaxy nexus. Here are some of my specs, and then Ill post some data graphs:

-I have a 3800mAh 3.7VDC lithiom ion battery, looks like this: http://www.ebay.com/itm/3800mAh-Ext...770689?pt=PDA_Accessories&hash=item4167963201
-I have NFC and Bluetooth turned off
-I have not done any undervolting, yet
-I have brightness at bare minimum
-I am only running on 3g
-I run a primarily black background
-I followed this guide for screen settings: http://www.ebay.com/itm/3800mAh-Ext...770689?pt=PDA_Accessories&hash=item4167963201
-this was done not playing any games, maybe only 2 min of youtube videos, primarily just light browsing, some mp3 playback, and reddit.
-using JBsourcery 2.5 rom
Graphs:
Before this test I was charged to 100%, deleted battery stats. I have better battery installed now, I will post those results after today, see if those help at all
Can someone please give me some direction? Do I have a bad battery? Ive had it for some time, Ive always though the battery should preform better than it does. Please any advice would be great

Definitely something wrong with that battery. Maybe it simply isn't a 3900mAh battery as the seller says? Or alternatively you have a faulty battery.
Based on my experience you should be getting better battery life than that even on stock battery. With CNA 3.6.6 + Trinity a67 I've had screen on time of over 3 hours and total discharge time of over 1d before reaching empty. And those were with display brightness set to automatic.

Hey buddy, from my experience, extended batteries tend to normally discharge to 1% normally, then it hangs there for many, many hours. The OS cannot detect the aftermarket battery size. Hope this helps.

I actually drained it all the way until it died, this screenshot is after it died

Im relatively certain now my battery is a dud. Can anyone recommend a battery? Is the seidio really my only option? Or do any of the other ones work?

I would try doing a battery calibration before buying another battery. It seems like a dud from what you've posted, but it won't hurt to calibrate it just to be sure.

And how do I do that? I already charged to full, wiped stats, and started from 100%-->0%

decided to go with just buying the seidio. I will report back when I have results

Alright, so I am noticing better battery life with this new battery. Realitvely high use, and getting better battery life. I havent been able to recreate the previous day yet, so cant do a comparision quiet yet. But really weird thing happened. I was having some network problems, rebooted my phone and plugged it in. It went from 16% to 42% instantly. Da faq? Anyone have any idea why this would happen? Are my battery stats messed up? Please help

Good battery replacement

My battery is running out after 2 years and more usage. What is an excellent replacement for desire Z/G2 battery?
Thanks

Anker 1600 mAh. Have been using it over 6 months now. Easily keeps my phone up at least 30% more than stock battery.

I bought a HTC original battery from eBay for the Incredible S for about 8 EUR. It's the same battery as ours, only with more capacity, 1450mah.
I also had an old battery, at least two years old. The new one's performance is incredible, almost two days with medium usage. Using Gen.Y VisionX R3.

I plan on picking up a new battery soon, recently the phone has been randomly rebooting. I read this might be a battery issue, so a fresher, longer battery life can't hurt.

I've found that the problem with random reboots are the battery contacts. Try reinserting the battery a few times.

I'm using a Mugen 1800mAh, best money I ever spent on my DZ. Running a nice stable and optimized ROM I was getting over 40 hours battery life which was amazing with my usage patterns. It still fits into the phone using the standard rear cover also.

I got myself an anker 1600 on eBay
Can't wait to try it. Hopefully this fixes my random rebooting. Can anyone report back if the new battery fixed this problem?
UPDATE: IT fixed my random rebooting! my phone works great now. no problems what so ever. best money i ever spent

Good to know, thanks for sharing!
There are so many crappy "high-capacity" batteries coming from china... We don't know who to trust.
Thanks!

Hey guys, just bought an Ankers 1600mAh battery, does anyone know a good procedure for replacing batteries? And I don't mean take the back off... :silly: Do you suggest I do a full charge, wipe battery stats, replace? What are your thoughts? Thanks very much

HERE ARE SOME GOOD TIPS
personally i charge full the first run (overnight) then reboot in the am and drain to around 10% reboot and charge full overnight and reboot in am. then use it like always.
this is just what i have done for years and many will tell you there is no need to train any lithium based batteries... but it works for me so this is how i do it
most will also say that wiping battery stats wont help as they are cleared on a reboot but i do find myself doing it anyway (i have lots of pointless habits i guess)

I run galilio evo4 2000 mah for more than a year.
I run a capacity test, I got around 1600 mah for both battery after about a year of use. Witch is very good.
I got 2 batteries and a charger for 20 $.
Do the rotation of oem and those galilio to keep them in shape.

[Q] Battery issue

I have my i9250 on CM11, fancy kernel and one of the latest twrp recovery.
I just changed a battery from original one (1750mAh) to slightly bigger one (2000mAh).
Once I tried to fully charge it, it got stuck at 90% and charging process turned off, like the battery was fully charged.
Is there anything I shall do? Like calibration (if so - how to do it?) Or is it the battery that is being screwed and I shall get it replaced.
New battery is not original Samsung battery. It says to be Li-ion battery.

Try to completely drain the new battery and then charge it, without unplugging it, to 100%.
Break me off a piece of that Kit-Kat ROM!

Tried that solution, drained it down to 4% and then tried to fully charge. With no success, stuck on 89%.
I will call on for battery replacement.
And hey, grab that piece

Maybe discharge it to 0% till it shuts off and then charge it. If that doesnt work try clearing batterystats (sdmaid has that option for example).
Sent from my Galaxy Nexus using XDA Premium HD app

try to power off your device and remove the battery, for 3 mins or more then insert back and connect your charger untill its fully charged

Since its li.ion battery it shall not be fully discharged, may and probably would battery.
Waiting for new battery, probably will get it tomorrow and then will flash new snapshot of cm11 with full data reset. Hoping for positive results

Change thread name as I guess it is no longer battery calibration thing.
Got another battery and problem persists.
Let me describe the whole story from the beginning.
With my maguro, about 4 months ago, on original battery I noticed worse battery performance. It was getting worse and worse but fairly slow. After about 2,5 months (6 weeks back from now) my phone stopped charging up to 100%. The highest value it would get was 94% and then it would turn off charging. I thought that my battery is dying. After another 3 weeks it would charge up only till 90% and then stop charging. I decided that its about right time to change the battery.
Found substitute with 2000mAh. And the rest of the story is above. It would not charge till 100% (would charge only up till 90%), so I thought that the battery is dodgy. Got a replacement. With new replacement of battery I decided also to do clean flash of new 20140107 CM11 nightly. After clean flash I still get the same problem - my phone does not charge up to 100%.
Checked under *#*#4636#*#*: it says it is Li-ion battery, so in line with what it says on the new battery package (at first I thought they might be selling old types of batteries [ni-cd or ni-mh] under Li-ion labels).
Do you have any idea what to do?
Please be aware that I have already tried:
- draining and then fully charging;
- charging phone with phone switched off;
- gave a phone few minutes with battery out so it could somehow "forget the past";
- different chargers (dc charger, usb charger, car charger);
- resetting battery stats
Anybody any help? Solutions? Same problems in the past?
