[Q] Is there a way to override the battery capacity ?

I've recently tried a cheap high capacity battery, over twice the capacity of the original one (but, of course, twice as fat and heavy). While the battery charges to it's 4.2V and discharges down to about 3.5V properly (tested manually, with the multimeter), the phone keeps reporting the battery as 1230mAh, tracking it accordingly. This causes the phone to go from 100% down to 15% at about the speed it would with the original battery and then remain at 15% for a full day. Similarly, charging the battery makes it go to 100% twice as fast as it should, yet the battery keeps charging after it reaches those virtual 100%, up to the proper 4.2V, with the proper current (NOT trickle charging).
I've already tried the obvious (fully charge, delete the stats file, fully use the charge, then full recharge again), it didn't really help, it only distributed the estimation a tiny little bit.
Any solutions ? Is there a proper way to manually override the battery capacity either with or without recalibration ?

Maybee battery curent widget... inside you have settings/monitoring/battery capacity...
But with that attitude I'm almoust sorry to help you

I am familiar with that widget, overriding the capacity setting there only changes the displayed capacity in the app, it doesn't affect the estimations at all. Sorry, i should have mentioned trying this.
PS: What attitude ? Bumping a thread that got buried on a third page after just 2 days, without a single answer, while most other threads that bury it could be answered using a search button ?! I can assure you, i may do it once again after a week+ or something and then i'll just forget about it, you can check my others threads And yea, they usually remain either unanswered, or self-answered after all (rare, but if it happens, i post my findings in the thread)
PPS: If you consider it such a "bad attitude" just don't bother helping. Thanks.

Battery reading is indeed not 100% perfect. But what ever change we would make. It is not gonna give you extra battery life. Until some one fix it there is no way to read it 100% correct. So that is the whole story.

Well, i don't bet on it to be 100% correct, but it should be something relatively close to the reality, while in case of this particular battery it's nowhere near that.
It assumes 1230mAh, calibrated or not, and i am 100% sure it takes this value from somewhere. In any case, it should be possible to patch, the question is where/how. Since i am not exactly an Android/Linux guru, the only things i did to find it out are searching this forum and doing simple google searches, finding nothing beyond the usual calibration thing. I though maybe someone may know something, that's why i posted the thread. I guess i was wrong about it.
PS: I guess i'll either abandon this, or start my own research, beginning at the source code of the ROM/kernel i use

i think you just need a rom/kernel that support extended batteries.

Tytung R10 does. All those kernels only support "official HTC extended battery" though, and i have yet to find out what does it really mean (read - what's the technical difference between the official and unofficial one). Note that the battery is charged/discharged properly, its just the stats/percentage remaining that go haywire.

mhh, just made some researches...
Stumbled over these threads:
Crazy, that there is a different behaviour if you have an orig. HTC or not...
http://forum.xda-developers.com/showthread.php?t=756513
http://forum.xda-developers.com/showthread.php?t=948181
Also read somewhere, that you really need to charge your phone to fully 100%, so that current widget shows 0ma...and then let the phone a few more hours at the charger, (DONT remove your charger) then manually delete the batterstats file in /data/system, turn off the device, REMOVE the charger, then boot the device.
Good luck

For those really interested to know what the technical difference between those bats... its the thermistor values range. Thats it.
The different batteries are identified by that thermistor value, all the batteries parameters are in the "ds2746_param_config.h", the table i am interested in modifying is the FL_25, one that defines the full battery capacity.
Sadly, this, most probably, requires a kernel recompilation, something i can't do, not without setting up all the required environment first Or, maybe it's possible to just patch the kernel image with hexeditor, i'll probably take a look.
PS: Thanks for everyone for trying to help.
EDIT: patching zImage would be harder than just recompiling it

not saying this is the right answer or that you haven't already tried but it didn't half help me out as i was only getting 8 hours before i used it, and i only got around 15 hours when i used to use wm, also left a print screen of what i get after i use the features in THIS page...

New battery 5000mAh

Anyone had heard about this new battery if yes any feedback?
http://www.alibaba.com/product-gs/461721767/New_replacement_battery_for_Acer_A500.html
Thanks

What is the capacity of the stock battery? I am impressed by how long the stock one lasts, but would much rather have a super capacity battery in there for an even longer run time.

IIRC, the stock battery is 3260mAh.

Correct, and there are actually 2 of them.
So does this mean we can have a pair of 5000mAh batteries? That would be awesome!

Actually there is only one, but this one is 2cell battery. Li-Po batteries come in cells, one cell is 3,7V. So you can build them like legos. You can add cells in series to increase voltage (1S 3,7V, 2S 7,4V, 3S 11,1V) or in parallel to increase endurance (1S 3,7V 2500mAh + in parallel 1S 3,7V 2500mAh = 1S2P 3,7V 5000mAh).

Is there a teardown guide for our tablet?

Yes, several of them.

So would this battery have a longer life than the stock battery?

Theres two 3260 bats. In teardowns it looks as though its one because both are together.

Nop. Only one, but inside this one are two cells. So only one battery.

Theres two 3260s. Not one. If there is only one 3260 I doubt our tabs would last as long as it already does. Call it one or two batteries whatever, like the specs say, 3260x2

Look. There is only one battery 7,4V 3260mAh 24WH Li-Po in our Iconia. Inside this battery are two Li-Po cells each 3,7V 3260mAh connected in series so capacity remain the same only voltage is doubled. My laptop has 9 cell battery but I'm not saying that I have 9 batteries. You can google by yourself for battery code 934TA001F you'll see only one baterry.

Ok. Sorry. Geegz. I still love you.

It's annoying, isn't it? So many people today just don't know the difference between a cell and a battery. Makes you wonder what they hell they teach in science class these days...
For those who get confused... A battery is ONLY a battery when there are multiple cells inside, linked either in series for parallel. If there's just one cell, then it's NOT a battery, it's a cell.

has anyone tried buying this yet and see if it works

They didn't teach about batteries in my science classes in highschool, nor in college. That was all in an electronics class I took for my ANSI certification.
Good luck buying one, minimum order is 100. I wonder what price per unit is, I'll email them and check details. I've made orders through them before, it's not too bad.

[HARD MOD]Dock + 750GB HDD + Double Battery

Edited 01/04/2012
If you're about to ask me if I've considered an ssd instead, know this. I may be an idiot, but I'm not that stupid. My IQ may be around 30 or so, but It's just high enough for me to figure out that an ssd is a much better option than an hdd. Jesus christ, stop asking this question already. The reason I've opted to put in an hdd instead of an ssd is because of cost. It cost me about $50 to for a 750GB hdd. An ssd with the same capacity will cost an arm and a leg. Go ahead and look that up.
So, please, if you're going to suggest I use an ssd, consider reading the above paragraph. And if you're going to email me telling me what an idiot I am for using an hdd instead of an ssd (like that turd a couple days ago), then also consider pushing the donate button right below my name so I have enough money to buy an ssd with comparative capacity. Goodness...
People, just because this is the internet doesn't mean everyone else beside you have an IQ of a potato. Get over yourself already.
****************************************************************************************************************************
I'm making a new thread because this is an entirely different mod than the other one.
So, I've added 2 more battery cells parallel to the other ones, doubling the capacity while maintaining the voltage. in addition, I've also added a 750 GB HDD.
Unlike the other mod, which suffered no deformation, there is a little bit of deformation in this mod. I can still close the netbook form. And if you look, you can see the curvature of the keyboard dock. It's not very noticeable, but if you know it's there you can definitely see it. Here are the pictures. I am currently testing out the battery capacity to see if it's really doubled like it's suppose to. We'll see, I guess.
By the way, while I am very happy with my result, despite the slight deformity to my dock, I definitely recommend against this for anyone else.

Speaking of which, how do I recalibrate the battery indicator? Looks like it's dropping at exactly the same speed as before.

I'm new to tablets, but on my Android phone you can run a app like battery calibration and it deletes batterystat.bin file.
Btw, cool mods I would be really interested in double battery.

It only affects the tablet battery. I can't get a definite answer from all my searches how to recalibrate the dock battery.

Aw, the deformation is a no in my book, but I think the mods themselves are awesome. If I tried this, I think I'd go for more batteries because I can't find enough stuff to fill my 32g usd cards anyway.. (or a secret compartment storing unmentionables).

I don't blame you. The deformation is hardly noticeable, but it is there. I'm actually happy with this setup. The slight deformation doesn't bother me. As long as I can still close the netbook form.
Now, if only I could find a way to calibrate the dock battery.

Impressive work! Let us know how long the battery lasts.

Well, I gotta figure out a way to recalibrate the dock battery first. It's dropping at exactly the same rate as when I only had 2 cells. Can't freakin' figure out how to do this.

By the way, I think I saw that you said your method is more refined and less risky now in another thread; is the method different, or have you refined your skills? If the method is different, could you post a tutorial? I think I might attempt it after I find out if I got into any good grad programs.. (because then I will know whether or not I will have some amount of money to burn for no damn reason ).

Both, actually. Before, I was both stumbling around blind and doing things in not so efficient and safe way. My soldering skills have improved greatly and I have also refined my procedure to involve no risk at all. It's all in the wrist, man.

Uh... no. This mod voids your warranty. I will take my methods with me to the grave.
PS - Isn't it obvious from the photos?
Added by edit.
Ok, my conscience got the better of me. There is something I left out of the photos. A key ingredient to making this whole mod work. Without this very simple but critical thing that is covered up by other components in the dock, the mod might as well be a piece of brick. It took thousands of hours and millions of dollars of research to figure out this one small piece of modification to make the whole thing work. My dock was sitting there for almost a month dead before I brought it back to life with this thing I'm speaking of.
In other words, don't try this. Trust me, you'll regret it not knowing what this thing I'm talking about is. It took me a whole month to figure out this thing. Thinking back, my goodness, the solution was so simple. And yet it took me a whole month to solve it.
Added by edit again.
I just figured out how to make the deformation go away. Damn, why didn't I think of this before. I'm too lazy now to open it up and apply the fix.

Are you not worried about charging two separate battery cells without a load balancing charger? At least from the RC world, this is a big negative. Fire can be no fun.

Exactly right, lion/lipo batteries need to be balanced in charge otherwise you will burn out the batteries and in extreme cases, BURN the batteries.
Having said that, many/most of the lipo batteries I have worked with in electronics have balancing circuits per "cell" so in reality you can simply add them like any battery and they take care of themselves. If lipo batteries were purchased without that circuit, then they are very cheap to buy and add as well.
I havent cracked the transformer, and dont plan to because the stock battery life is plenty for me; however, I have increased the battery capacity on several laptops, and other types of devices, and the first key is to ensure the cells are balanced before connecting them together, then ensuring you have a balancing circuit to EACH cell otherwise over time they will come out of balance (normal use and internal resistance). Once you have done those two things, you can connect them and use them.
Now, the other point is the meters. I have no idea about the transformer but most battery meters work simply on the voltage on the batteries and assume the discharge in a linear fashion. This is rarely true for batteries, but it is simple, cheap and gives you an idea about how much power you have left. Sometimes this is error is covered by software that "maps" the battery discharge rate and gives you a "real" battery left level. So to the point of all that paragraph, once you balance the batteries, connect them and run through a few full charge/discharge cycles, you will likely find that the meter will catch up.
A point of caution, the word "cell" does not refer to a nicely packaged lipo battery with two wires. A cell is a single constructed unit that is usually 3.7v in the lipo world (different chemistries of batteries will have different voltages). If you added a pair of 3.7v (1s1p) batteries in parellel with a pair of 7v batteries (2s1p) you could really confuse the battery meters.
Enjoy the mod, I love reading about them..

I just redid the mod. Unfortunately, it was 3am and I forgot to take pictures before I closed up the dock. But basically what I did was charged both batteries up to 100% and connected them in parallel as is with their balancing circuits. Before, I took the cells out and added them to the circuit of the other one. This time I kept the circuits and added the circuits together.
It seems to work. The new battery pack is recognized. We'll see what happens later.
Here is a picture to give you an idea.

Wrong battery percentage

Hello everybody!
I have a Note 3 N900, 5.0, L19, dr ketan rom. This problem existed even on stock, and on stock KitKat.
I have a problem with the battery percentage. The battery percentage goes down at a rate of, for example when browsing the web on Chrome, 2%-4% a minute!
Overall, the battery life is not good during to this problem, as you guys can imagine. Tried to do a battery cycle (emptying the battery and charging to full) with no success...
Bought 2 new (!) batteries, but still, with no luck.
What the he** can be the problem if not from the ROM itself?
Thank you!

Idk if I've been cursed at or something, every device of mine needs to go to repair at least once in its lifetime.

Can you give us more specific info about what's using your battery?
Install BetterBatteryStats and send some screenshots, this is an extreme problem I can tell. There must be something keeping your phone in full power all the time.
How hot is your device? Believe it or not, the battery gets affected extremely by heat since it Lithium-ion.
What apps do you have installed? Apps like Facebook and similar will cause consumption.
There's a lot of things that affect the battery.

Take a look at these.
I, personally, can't see anything special. Do you?

According do those screenshots you have excellent battery life! I don't even get half of that. The screen of your note 3 takes up lots of power. What I can suggest is to change you max Cpu frequency to 1490mhz and go for the intellidemand governor. The snapdragon 800 is powerful enough to run smoothly with that frequency. Try it and report back if it did any changes.

Oh right! I'm sorry, I missed that part. But just try to underclock your CPU a little bit and you should see a increase in battery life. Just try whatever frequency you want, the only thing that might happen is a slow device (you basically can't break the phone with underclocking, in fact, it's better for the CPU). Remember to change your governor to Intellidemand or Intellimand (can't remember the exact name).

I don't think that there are working custom kernel for the 5.0 N900... shame there's almost no more development for our phone..

i have this same **** problem

Ok, even with two new batteries and a few battery cycles with them, the percentage won't stabilize... Today the battery ran down to zero, and the phone continued to run (on 0%) for about 20 min..............
After replacing the battery, I was on 100%, dialed *#0228# and did the "RUN TEST" and the percentage went down to 23%. Dialed again and it went up to 82% and charged it. I can't seem to find a godda** solution for this problem!
What can I do to solve this?!!

Poor battery no matter which rom

I've been using several different 7.1.2 roms and battery life has been atrocious. I use wingoku 4.1.
I pair my smart watch to it but even when I use wifi (no bt) its bad, draining quickly, last checked about 22% per hr. Even with screen off listening to podcasts it still will drop a lot more than it used to.
I really don't have much in terms of stats. Honestly I don't obsess much about it normally but now its noticable.
Aside from suggesting another rom & kernel, would I benefit from formatting data and starting over?

Install accubattery and run it though a few charge cycles, it will be able to tell you the life left in your battery, it's possible that you have the same issue many of us have had with a degradation of the battery.

Yea. Thats my biggest fear. Ive replaced small parts before but my eyesight isn't as good as it used to be so Im afraid I might mess it up. Plus I'll need to buy a heat gun.
I'll be more than a little pissed if the battery's shot. This phone is barely 14 months old. Either give us a decent battery or make it replaceable.
Thanks for the info btw. I just installed the app.

Update--Im switching things up a bit. Recently I made some changes and this time I flashed a new rom without some of those changes.
1. I had switched from Action 3 to Nova
*HIGHLY doubt nova is eating up my battery so Im still using it BUT I did remove a widget that has weather. Since I keep phone on device only location, I think theres a chance its always trying to find my locale and consuming battery.
2. I didn't add a gov profile yet.
3. This is the first time in about 4 or 5 rom flashes I didnt flash CTT Mod.
* Again I doubt this is causing battery issues but Im gonna hold off flashing it. No throttling thus far.
As suggested Ill be monitoring with accubattery for a few cycles. But been using my phone about 90 mins this morning (at least 90% of that time actively using with screen on) and I've lost 13%--a huge improvement from yesterday.

Accubattery for the proof. New battery for the fix. You could always buy online and have it installed locally. Read up on where to score a good replacement battery, rather than another dud.

Thanks. But for now it looks like my battery is ok. I did a follow-up post above. And to follow-up on that, Im still getting good battery life.

Okay, sounds good. What does Accubattery report your battery health as? (health tab)

Its not really giving me much info yet. Because of my schedule throughout the day Ive charged periodically so I have enough juice in case I need it. Do I need to let it run lower to get an accurate reading?

Best to let it run below 20% at least and then fully charge until the APP tells you the battery is full- not your phone. Don't unplug until Accubattery says it is full. What you will observe is that the phone will continue to charge for 45 minutes to an hour past when the phone itself is reporting 100%. You will find the estimated capacity under the Health tab. Once or twice below 20% is enough to get a close approximation. After that it will move a couple percent max. You will know soon enough.

Well it turns out my battery is in need of replacing.
I let it run down like you said. I was going to go further down but once it hit 20% my phone turned off. I plugged it in, opened accubattery and it said 46% under health.
But I just checked again after charging to 100% and it now says 63% (2182 mAh total capacity).
I checked my imei on the Huawei site and my phone is 3 days out of warranty. Im hoping to get them to fix it.

Well sorry to hear that. Good luck to you on the RMA route. If not, the Cameron Sino brand replacement is a bit more expensive but includes a working battery temperature sensor. It will make your phone like new. Note in the thread I referenced above, some parts may get scratched/cracked depending on the skill of the repair person. They aren't expensive so it you are intending to keep the 6P for a while longer, it may be worth it to buy those just in case.

Thanks for the support! I checked that thread and didn't see specific parts (inexpensive ones you referenced) If they're listed Ill look again. It doesn't seem too daunting. I was able to replace the screen on my son's WiU controller. Those were very tiny parts and YES--I did snap off a clip, however I was able to fudge it and it's still working about a year later.
Far as RMA, does anyone know if they replace it with the same crappy stock battery? From my perspective this seems like a clear case where a recall is in order.
But if its the same battery, Im just setting myself up for the same problems 8 to 12 months from now. Even if I buy a new phone Id still want to sell this one and thats not as easy with a crap battery. Plus theyd have my phone for x days so Id need to find a temp phone in the meantime.
Don't mean to jabber on...this sucks.
Oh yeah...cuz it was after hours I sent an email to support last night. Do you think Ill get a response? Or should I just call when I have time to be on hold?

Spoke to a clone at Huawei then asked to speak to the clone's supervisor (wasn't sure if clones had supervisors--they do. But the programming is identical.) Long frustrating phone call and they aren't going to replace my battery because its out of warranty...by 4 f#@&ing days!
I told them they lost a customer for life and I was being 100% sincere. How could I ever buy from people who thinks it ok to sell defective crap, know about it, then do nothing to make things right?
I'm gonna replace the battery on my own. Whether things go good or terrible, one thing is certain--itll be the last time I ever replace anything on any product made by Huawei.
