I just bought a 1900mAh battery off ebay, and it came from china, so Im unsure if it's really 1900mAh, because my 1520mAh weighs more...
How can I check if it really is 1900mAh?
I think that the only way to do that is to fully charge the battery then drain it fully while measuring the current and see if it would last for 2hrs if the current is 950mA. Thats the way I did a few battery checks while I was studying (telecommunications). But everything is done out of the phone, exept the charging. Hope it gave you an idea how it is done.

Is there any way to check the mAh of a battery you just recieved. I ordered a 3500mah one off ebay and just want to make sure that it is the same mah as stated. Is there a program or some way I can check this?
Thanks
Typically you'll need a device, or some system to discharge the battery at a constant current, and then measure the time it takes to meet its final voltage, and you need to watch it to make sure you don't kill the battery. Plus the life also depends on the discharge rate so you may get more than 3.5Ah out of it if you discharge it longer with a low current then visa versa.
Also typically batteries you buy on ebay don't normally meet the rated life.

I just bought a 3500mah battery from ebay. Its only gone through 1 full discharge but assuming my Samsung battery is 1500mAh I'd estimate the ebay one to be about 2200-2300mAh.. hopefully it will increase after a few cylces and calibration
I bought that battery, and it's definitely not that good, Idk if I got a bad one, but my phone only last about hmm the same as the stock battery.. I wish I could check the mah
I was reading around the forum and through all the things about extended batteries and stuff to decide that I was going to buy the Mugen 3200mAh one.
My question is Droidzone has this thing called "EBatt/EBFix=Droidzone's fix for Extended Batteries". Do I need that for my extended battery or will it have no problems with charging? I believe his fix is set for 2400mAh but mine is 3200mAh.
I put in my extended battery and it was at 0% charge, only thing I notices was Battery Widget Widget Pro didn't know how many mAh so I assume neither does the phone (because its not an official HTC battery).
I'm doing what the Mugen User Guide is telling me, which is to charge the phone for 8-12 hours even if it shows full charge for the first 4-5 times.
Correct me if I'm wrong but I'm assuming that the battery will charge but take a longer time to charge but will still show 100% (also will the battery % be completely wrong all the time because the phone doesn't understand the maximum capacity is greater now).
So back to my initial question, do I need to flash a extended battery fix kernel or just calibrating the batteries should work?
As far as extended batterys go, yes you need a kernal which supports it. I'm shopping around for a Yoobao battery and I'm finding out which kernal I need which will support the information for the battery.

Any luck on finding one? So the battery won't charge to full capacity without the appropriate kernel?
With the kernels I've only found droidzone and I don't particular have the time to test all the different kernels on my phone.
I tried doing the full charge without using a different kernel, I will see the results of this soon hopefully.
It should charge to full but you won't see the real capacity.

Mine charges to 54% then jumps 100$. It doesn't seem to be giving me the full amount I expected. It charged more once for an hour or two after I let it get to 99% then switched off and charged again. Then booted and let it hit 99% and repeated the process about 3 times. Then I wiped battery stats. Now I'm letting it relearn the whole battery thing. It's dropping fast right now... But I think a few full charge cycles are required.
No. You do.not need a special kernel. Mugen battery's are made to.be used with nonroot phones.

Hi everyone,
I've had my Sensation for about 14 months now and for the past month I've been having battery issues. Primarily, it's very quick to lose charge and will lose charge even while charging from the wall. First I bought a replacement battery but was still having the same issues. I've started using Better Battery Stats and Battery Monitor Widget but I don't have anything out of the ordinary running. In fact, not a lot is running at all. BMW has allowed me to see how the charging is going though which has been nice. During this period I have used Elegancia, Bruce's CM10, and am currently on ParanoidAndroid. All experienced the same issues.
Last night, for example, I put the phone on the charger at 16 percent. It charged up to 22 and then started the downward slide to death and I ended up waking up 35 minutes late.
Where do I go from here so I don't have to constantly be paranoid about my battery levels?
Sounds like you might need another battery. In better battery starts did you notice any unusual wake locks? This could drain a battery. But since it looses charge even when charging I'd think it was the battery. I personally was experiencing some battery issues myself finally I broke down and got a mugen 3800mah battery from mugen. It was expensive but really worth it for Me.with really heavy and constant use I get 20 hours out of my battery, with normal use I get two days. I'm also running paranoid Android rom. For me the big battery solved my issues. Only one draw back, it does make your phone thicker. New back included with battery. This didn't bother me much because of the excellent battery life I receive. Now I finally don't. Worry about battery. However it's expensive at about 95 dollars. But I was so fed up with poor battery life it was worth it for me. You have to be careful when buying inexpensive batteries because there are a lot of fakes going around. And the mah is not really what it says it is on the packages. You can test the battery and make sure it is what it's advertised to be. If you don't want to go with that large of a battery you can also try anker extended battery. It's a lot less expensive and is a good battery. I personally needed more juice so I went with the big battery. I know you said you replaced the battery but sometimes the bargain batteries go bad quickly. It makes me suspicious of the battery because it's even dropping while charging. This is strange. If you ruled out any apps or wake locks that might be draining the battery I would buy a good reliable battery. The draining while charging is a red flag. I'd say the battery is going bad. I don't at all regret my purchase of the big battery. It for me, solved my issues. I do Hope this helps and I wish you the best. Hopefully you will get your issue resolved soon.

its either an issue with the battery or the battery reporting.
Only thing you can really try is to charge it up to 100%, wipe battery stats in recovery, then let it empty totally and charge it up again, see how its behaving. There is a chance that its the reporting that is off.
otherwise this looks like the battery is on its way out im afraid

Argh. I hope it's not the replacement battery too. I got a replacement HTC battery. The problem I'm having getting anything useful from Better Battery Stats is that rarely am I off the charger. In the settings it says I can log while charging but it may mess up the stats so I've shied away from doing that. I'm not against getting a bigger, better battery but I would hate to do that and have it actually be something else hardware-wise where I would need to get rid of my phone.

I'll give this a try if I can get it back up to 100%. Is the reporting in Recovery always correct? The battery never has issues charging while it's in Recovery mode. If that's the case then I'll charge it to 100% in recovery and then wipe and start fresh.
Thanks
I don't think it's the battery. This phones have errors in battery readings. I feel your pain man. Mine is from T-Mobile (Sensation 4G) and it discharges if I use it even at lowest brightness when it's charging too.
If I reboot, I get the battery boost. I have tried EVERYTHING I read here and nothing worked. I even have 4 batteries. All of them in good condition.
I even tried three times discharging it fully and without turning it on, charge it in the night and when I wake up 7-8 hours later, it's still charging. I tried wiping stats, changing ROMs, changing the usb cable and the charger. Everything... I believe it's a hardware issue. (Thank HTC for that) I'm not buying another HTC when I have to upgrade.

Interesting...so if you were to charge the phone in recoery how long do you think it would take to get to 100%?
I would definitely do what you said, charge in recovery then wipe battery stats and go from there.
If you're interested in having something to compare to, it takes my phone about 3 hours to charge to 100% (by the way I'm using an Anker extended capacity battery), with a peak current usually around 800 - 900 mA. Fully charged I have somewhere around 4100 mV. If you haven't already, I'd suggest adding a Battery Monitor widget with mA, mV, and % available being displayed and it will be pretty easy to get an idea what's going on.

I'm leaning towards hardware issue too. That's why I figured I'd post and see if there was anything else that I can try. It's also why I don't really want to buy an expensive battery since who knows what it'll fit next. I know what you mean about the reboot battery boost. You can almost gamble and bet on percentages when you reboot. I've seen 50% swings before.

In recovery I would guess that it wont take very long to charge to full. I have battery monitor widget installed and while plugged into the wall with my 1.0A charger, it will typically pull 100-200mA but sometimes it'll spike to 700-900mA. No rhyme or reason. When idling and functioning properly, without a charger plugged in it drops 9-100mA. Sometimes though while charging it'll sit at negative 100-200mA.
HA! Just rebooted my phone and it went from 68% to 100%. So I rebooted into recovery, it also said full so I wiped stats.

I normally get 2 to 3 mA drain with the phone sleeping. When charging you may not necessarily get close to the 1 A current delivery of the charger straight away, typically it will ramp up over time and reach peak charge current as it gets closer to 100%. Once at 100% it wants to just "trickle" charge to maintain 100% charge until the charger is disconnected, so any wakelocks etc. that cause a current drain during that "trickle" charging will actually decrease battery charge until the charger ramps up to compensate for the drain. Random spikes in charging current would suggest a hardware problem where the electronics are struggling to properly govern the charging process, as would a large negative current drain with the charger plugged in. Silly question but what's the actual plug connection to your phone like? Nice and solid, pins all OK?
Hi Guyz,
I have bought a new Anker battery via Amazon. But the problem is it gets to 99% very quickly from then on, it takes hours and hours to get to 100%. And the discharge is also a problem - from 100 to 70 its very slow. Then to 40 percent its very fast etc. I have wiped battery stats, calibrated the battery, changed many roms but still the issue persists. Am i doing something wrong ?

It's pretty normal their batteries perform like this. You can switch to a different brand if you wish. I've tried RavPower and Mophie and I don't see these problems on them. It's always good to try something new.
So far i got two Anker 1900 batteries for HTC Sensation and both had same issue as you described. But that's really not an issue because you just need to charge your phone until it's 100% fulll and it doesn't matter if gets quickly to 99% and then needs some time for 100%. Also it's fine to leave your phone charging every night so you always start your day with fully battery. Other than that insignificant issue, Anker batteries for HTC Sensation are one of best choices, especially if you are looking for value for price.
Hi guys, have you guys ever bought a replacement battery for your p30 pro ? mine is finished. It drains very quickly. I'm thinking of buying one and install it, Has anyone has one to recommend? like where to buy ? link?
there is many out there, but i want the original one. I dont trust those on ebay.
thanks
Nope, mine still holds on really well.
Be sure that there is no app draining your device. Or that your charging habits are okay.
For better battery health:
Try to only use the Huawei charger, and no cheap chargers.
Battery performance degrade faster after full charge and drain, so don't let the battery die too often, it is recommended to charge your phone often. Partially discharge is healthier than (almost) full discharge, they advice to not go below 20%.

Standby time is okay. SOT are about 60h after a full charge.
as soon i use the screen, regardless the apps, it starts to drain very quickly. Per. google dua (video call) 25% gone after like 35mins of using. Or if i play games, it kills even faster. Although, I set to the screen brightness to lowest enough so i can see.
I have p30 pro over year, and I am heavy user but battery is still fine, as advised before check for apk issue, must be something there what drain your battery, way to early to replace battery, and battery will be still covered under 2 year warranty, but there will be apk issue, record all apks, and start removing one by one, this way you will found faulty apk in your phone, good luck.
Never used Quick charge, never use phone while charging... Before this afternoon I rebooted the phone at 33%, when turns on again it shows 14%.. And in this last week I notice often that battery quickly discharge under 20-25% (just like 5m of sot 22% to 5% and phone goes to sleep) I'm so disappointed by this phone, after 13 months of use...
me too, i'm looking into one...if you guys ever got one to suggest

Does that mean you didn't use his charger, the original one ... ??
Then you complain that his battery is destroyed ...
