Question regarding extended batteries

Couldn't find it through searching so if someone could answer this for me, it'd be great.
I'm considering purchasing an Incredible, but am definitely thinking of going with the 1750 or 2150 extended battery. Do these calibrate correctly with the phone's battery meter? The ones on the Droid 1 do not, Droid 1 users have to reboot to see their actual usage. If it would contribute to a more accurate answer, I will most likely be running custom roms with 1% indications. Thanks

Yes, best I can tell. I have the Seidio 1750 and I have to say, if you don't mind your phone being a little thicker I'd go with the HTC 2150. I still barely make it through a full day with moderate use.

Yes they read correctly, just bought the 2150 yesterday. Thought it was defective due to it taking 8+hrs to charge from 56%, but it was my usb cable. Sad thing is the phone is only 1wk old. Got it on a two year contract, not a CPO either. They do provide a better experience versus stock. Got 12+hrs of heavy usage, without bump charging.

Thanks for the replies. Yeah I was considering the 2150, but I don't like added bulk (kind of the reason why I want to switch from a Droid to an Inc). I like what this guy did, but have no experience whatsoever in dremeling http://forum.xda-developers.com/showthread.php?t=703332

I bought an 1800 battery off eBay and it fits tthe normal back so no bulk

Thanks for your opinion. One more question (I hope this isn't a stupid one) do I need to look for special roms for the SLCD incredible? Or can I use any ROM?

I have the 3700Mah battery and I end the day with 30% lol.
The added bulk is all good because with the new back it's a perfect square.

[Q] Use two different Batteries

Hi beloved Defy users (you may decide yourself, who is beloved )
I just asked myself if it is a bad idea to use two different batteries, e.g. always or often drain one battery and then use the other (for me this is not an odd situation, if you think about camping or long trips with GPS).
So, the question is, what about those somehow built-in battery-calibration-algorithms of the Defy, or in general of such devices? Will they get a blow on their head when one batterie (the 5$ one from ebay, you know, those explosives) is behaving totaly different from the other (stock) one?
Is there a possibility to manage different batteries without getting wrong percentage-estimations? Or am I overestimating the whole situation?
Have a nice weekend

wipe battery stats in recovery, menu advanced.
And this forum is for development, you should post this in general.

Oops, sorry, I intended to. I hope some mod will move it
Wiping the battery stats with each change isn't gonna be usefull, as changing the battery after each cycle would mean having no stats at all.

Sorry to revive this old thread mates, I should post a new thread but I think it is better to stick on this and just ask the same plain noob question for the experts to answer..
And since there's no concrete answer yet to this situation I think I still need to ask again if there will be an issue if I will be using two batteries at the same time due to somewhat long journeys or long time playing of music while on the road so I really need some extra battery just in case my stock batt. will got drain which 100 percent I know will..
Well I hope someone got some input about this..

How about a 2in1 battery?
And by 2in1 battery i mean a big, massive battery that you could buy along with a new back cover for it. I have seen in some videos that smartphone users often prefer to use a big bulky battery that offers more energy than to use 2 batteries. I would do so myself.

well I am on ICS right now, perhaps the battery bug won't occur on this ROM so perhaps changing from another batt from time to time won't confuse the system.

silly. as soon as you get one of the huge batteries, you will want to use the stock one as a back up, and back to the original question
So, do i still have to worry about reset battery stats after the phone die with the big battery inside and i start it up again with the wimpy stock one?
And is there any issue with using the phone turned OFF to charge one battery after the other?

Extended battery issues

I purchased a really cheap extended battery about a month and a half ago on amazon and it practically doubled my battery life for a while. Now for some reason its no where near that performance and will only last me a day or so. I already wiped my battery stats, but no luck. Any suggestions would be much appreciated!

OMG ONLY A DAY?! YOU POOR THING!
No really though. Maybe it's an app you've downloaded recently. Do a full wipe If a full day of battery life just isn't good enough for you.

Any of the ext batteries good??

May I ask what the battery was? I got a really cheap one off amazon that is supposedly 3500mAh, but it only has a slight difference in charge time =/

Hey,
I got the same extended battery off amazon, it works amazing, anyways there are several things that could be causing this issue:
1. Like someone posted before me check your apps, see whats running. Make sure to look out for the new ones because it might be running in the backround where even the task killer cant reach and killing your batter D:
2. Are you using gps 4g or any other features like that?
3. If you are rooted did you just flash a new rom? because with different roms you will get many different factors that effect your batt, with MIUI I would get over a day on the standard battery, and on sense roms il get maybe only half a day.
4. Those cheap batts are made for little and sold at little from China, so the quality isnt always the best, and it might be time to get a new one!
Hope I helped! and I hope you find a solution! good luck!

Since this a very old post, I'm sure that you've already resolved the issue. It has been my experience that while L-ion batts don't have a memory, their ability to take a charge can be affected by inadequate initial charges and NOT running them totally dead, at least once in a while. Whereas wiping battery stats will help the phone's OS to ensure maximum charge and usage, the battery still needs to go through a full cycle.
I hope that I'm not wearing you out with crap you already know. (Let's just assume that someone else needs this information, too).
Now to get REALLY nerdy:
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Read that if you really want to understand L-Ion batteries.
Then, you could just have a really cheap or bad battery pack. BTW, what's that brand again? I'm about to buy one myself...LOL.

HTC Evo 4g rom help

Hi I currently have mikg rom installed on my evo but my battery life is still horrible,, does anyone know any roms that use less juice on the battery.. thats all im really concerned about? thanks

I always liked the TN Shooter ROM. Sense 3.0, working 4G, life is good. I cannot say anything about battery life though, because I use two extended batteries, but from what I can tell battery life isn't too bad. Link --

How old is your battery? When i first rooted my EVO, it could sleep overnight and lose 2%, and after a year, it wouldn't stay on 100% for more than 30 seconds. I could literally sit and watch the battery drain at this point. Age I'd a big factor in determining the battery life.
Another big factor is whether or not you are using an HTC battery, or if you purchased a 3rd party battery. Just keep those things in mind.

First things first. This belongs in Q/A . That being said. Did you do a Clean Install of the Rom ? Did you restore any Data ? What Kernel are you using ? Also this has been mentioned, but I will reiterate. If your Battery is old, or if you are using a knock off Battery it affects the Battery life.

After a long period of battery use,it will degrade as time goes on and you will lose battery cells and the battery gets weaker and wont keep a full charge,the best practice is to charge your phone fully,then let it discharge until it shuts itself off,then recharge again and do the same thing,then recharge and the battery will stay charged a little longer,is what this supposidly does is try building the cells back,but its only temporary,especially when you have an worn battery,the best roms to use for battery life,from my experience is aamikam and Tommys roms,alot of time it will also have to do with the kernel,especially if its an OC'ed kernel,look for an SBC(superior battery charge) kernel.

ok well idk what kernal it is because i cant figure out how to add one yet,, but maybe it was the batterys i bought this extended battery off ebay which had a high mah rating i thought it would last longer but it didnt wasnt a oem battery i didnt know there was a difference so i went ahead and bought a factory battery today .. thanks

Try discharging the battery than give it a full charge. If that doesn't help, try a Rom called SOS X/N.

BTW not sure if you have one or ever heard of anker batteries but anyways they sell a charger with the battery. My original EVO battery started to die very fast. I bought an anker and it seems whenever I charge the phone via USB charger vs the anker battery charger the battery will die much faster. You should try buying the anker battery charger & use the charger to charge your battery, do not use the USB cord to charge it & see if that helps any

[Q] battery life, what's yours?

Hi guys, I hope this is the right place for my question. I bought my galaxy nexus 1 year and a half ago, actually I installed the Slimkat rom but the battery life seems really poor, for example in this moment I've got 68% left with 1h of screen activity and 4.30h in general.
I don't know what's the average of the gnex battery life, but it would be great to improve it a bit. What's yours?
Can you tell me what rom can give me the best battery life? I'm not sure but I believe to remember that with the stock 4.3 the situation was better (not too much really), is it possible? shouldn't 4.4 be optimized to increase battery life? I've read about people with 4-5 hours of screen activity, how is it possible?
thank you and sorry for my english :fingers-crossed:

Generally, battery life for my 2.5 year old Gnex is generally not good. In fact, it's poor when new, and gotten worse over the 2 years. I'm using CM11 with Fancy R51. I think it helps the standby time significantly, although screen on time still suffers from the aged and small battery.
Recently, I made a pogo dock for it, so that I keep it constantly charged while I'm at my desk. At least it helps to reduce wear and tear on the micro-USB port.

well, I understand that battery life can't be the same of when I bought the phone but I read about people with 4-5 hours of screen activity with stock battery! I found a topic about cataclysm 4.3 rom where users say that it has great battery performance, unfortunately I can't post there because I'm a new user. I wonder if a custom rom is necessary or that's only 4.3 worth. Can I eventually flash that from from mine? Slimkat4.4? thanks

I bought my GNex about a month ago and had the intention to use the biggest battery available.
Battery: Zerolemon 5800mAh
ROM: latest CM11 release
My battery app: Battery Monitor Widget Pro
BMW tells me that the battery is actually about 5100mAh, but this average grows a bit with each full charge cycle. The problem is that it takes more than a day to run the battery down and more than a night to get full charge.
With the giant battery I don't worry about managing power.

3h's is the max I've ever got, but normally I only get 2h's.
Only way I ever see our GN would getting 4-5h's of ON screen time is perhaps if the brightness is set to the lowest level, using Wi-Fi only for data AND doing something that require very little CPU power (ie. not gaming/video).

Same. Never got more than 3h of SOT with the stock battery. Let it be Android 4.3 or 4.4 rom. I've tried a new OEM battery as well. The only option to get better battery life is to use extended batteries.

Giant battery with NFC!

Zerolemon looks great! Pity zerolemon doesn't have it for the GSM version. Does the purported NFC work?

NFC is wireless charging?
I only have a standard charger. Maybe some reviews of the battery on Amazon would be a good source for your answer. Sorry.

thanks everybody for the answers, it's a pity because my gnex still has great performance but I leave you imagine what happens when I turn on GPS . For those who talk about extended battery, can you suggest me a model? I read something about non-original battery and possibility of accident, what do you think? thanks

No, NFC isn't wireless charging. It's Near Field Communcation. The gnex is NFC-capable, but the antenna for the NFC is embedded with the stock battery. Upgrading to third-party battery usually disables the NFC functionality. Well, if you don't use it, you're not going to miss it.

Hmm, I will look into that. I don't know if I use it or not. I'm still learning about the phone, but very happy so far. Thanks for the clarification!
...
Ok, read up on NFC on Wikipedia and no, I have not yet used it.
However, one of the top rated "helpful" reviews of the zero lemon battery does mention that NFC does work. I am not currently in a situation that allows me to confirm it. Maybe someday soon.
