2250mAh battery - not performing good!

I purchased a new 2250mAh extended battery recently from megacapacity.com.
In a full charge it gives me 18-20 hours backup with 1 hr talk time only. I don't even use Wi-Fi, GPRS. Just simple calls.
Is it normal? i dont think. Original battery 1050mAh gave better performance when it was in good condition. What could be the issue?
I have tried almost every ROM but its almost same in every case.
Anybody having 2250mAh battery? pl share your thoughts.
Is there some problem with device not charging optimally or battery is bad?

2250
I have a 2250 battery purchased from megacapacity itself. The first charge lasted for 50 hours. The battery at the time of recharge was around 20% but I recharged again. I am sure it would have gone for another 10 hours at least.
This is with moderate calls, browsing, solitaire, always on Microsoft Push mail and lot of email reading and writing. I was basically testing the battery backup; so kind of stressed my phone a bit to see the actual backup time available.
On a related note, I was definitely not happy with megacapacity as they didn't send me the correct battery cover for vox and never responded to any of my emails. So now my phone is without battery cover. And I am planning to buy one more normal sized battery because of this. Thanks to megacapacity.

PS: - I am using fireburned 6.1 stable rom 1.4.

I am pretty happy with Polar CEll 1300 mAh battery. It gets me through the day with heavy use! It dies when I am IMing over Wifi for a couple of hours in the evening.

Is it device charging issue?
My device was also working good with original battery. I used it for approx 18 months. After that (couple of months back) it started giving problem shutting down device suddenly while in the call. Its calibration was totally disturbed, i happend due to high temperatures some time when in car, i think so.
In nutshell that battery was of no use to be thrown out. Then,
I bought 2250 mAh but its not giving expected performance, its lasts for max one day with normal use.
Could it be due to issues with device charging circuit? It gets charged fully in one hour. i suspect there might be some issue with device circuit.
or finally battery is not good?
Pl advise.

parthabhatta & h4waii,
You both have good experince with VOX battery, pl share your thoughts on this.

Hi,
Actually I use a battery bought from megacapacity but its 1100mAh. The battery is not giving me any problems and after a few calls, roughly one hour surfing and some music playing 20-30% battery is still left. So what I feel is being 2250mAh it should last atleast 80% more than 1100 mAh if not double. You can check the Power management battery bar while charging - whether it shoots up occassionally at random or gradually increases with increments of 1% till it attains 100%. If it shoots up, try with USB charging and see if the problem recurs. Give it a try and let us know.

Just be careful of using BIG battery.

Thats a good idea, sure i will check and let you know.

I charged my 2250mAH in an external charger, which removes any possibility of the device shutting off charge after it reaches a certain voltage. It allows the battery to make that choice. I had good use with it, very heavy usage and it would last drastically longer than the OEM 1100mAH unit. I'd recommend just buying a 1300mAH as the 2250 is very cumbersome to carry around on the device.
Again, I still have mine - if anybody wants to buy them.
There are a few issues with keeping the sheet in contact with the pins, else it will shut off randomly, I padded it with paper and pulled the pins out a bit.

i got mine a year ago from ebaystore dmc-batteries.
first i also got the wrong backcover, but they sent me very fast the correct one.
The battery is definitely not twice as strong as the original one.
At normal use I think the max is 1,5 day. Light use gives me 2 days but heavy use with bluetooth or wifi or gprs only 1 day.
as h4waii I had in the beginning some problems with the contacts and sudden loss of power because of that, but that disappeared with time

Still I can't make a point...I'cant determine were is good to buy (obviously referring xda user's opinion to how much the battery lasts) and where is better not to buy. LoL

dmc-batteries gave me good service and are quick and friendy in their replies. I recommend them.

Thank you birdibird , but my intention was a survey to know what brand (seller) of ezxtended battery lasts more than an other. Just that
Because I've read of battery lasting 4-5 days with normal usage and others not lasting more than 1!

[Q] Draining battery on first use?

Hi guys
I should be picking up my SGS2 today and I was just wondering what exactly I should be doing with the battery? I've read in a bunch of places that draining the battery fully and then recharging it fully gives better battery life, but I've also read this:
Lithium ion batteries do not respond well to full discharge, you will see reduced capacity and early failure if it happens too often. In any case it is not possible to overcharge the battery on a BlackBerry because the battery and phone have enough intelligence to control the charge (unless the battery is already defective).

(this is from crackberry.com but you get the idea)
What's the best thing to do?
And on Android phones, when the battery indicator shows 20% or something, is that when the phone is going to die? Or will it die at 0%? Obviously at 20% it would be to protect the battery but maybe Android has been programmed to show 0% when the battery is actually at 20%.
Thanks,
Elliott

read manuals !!!!!! You can see this

Did not receive an owners manual with my phone. Anyway...phone is charging now so too late I guess...

The manual is probably stored on the phone, at least my new Ascend II came with its stored on the phone, you have to goto the big menu (forgive me for not knowing the technical term for it) to find it however

i got my battery fully charged...then in the first day i discharged it till 10% at least that's what my phone was saying
i read too that the new li-ion batteryes do not need to be "formated" (fully discharged till the phone dies and then fully charged with the phone turned off) in android case i think that thing is not posible coz it needs at least 5% to pass the bootloader and then begin to charge
anyway in my manual it says that the battery will begin the normal state after 8 days of use, until then it may disschage quick
i have a motorola defy

Calibrate the battery. Charge the phone while its switched off for about 6 hours, and then use the phone untill the entire battery runs out and it switches off on its own. After this, the phone should be able to use the battery properly.

i just used my galaxy and made it empty, then charged it full.
nowadays i have runtimes from 3days (72 hours) and then its @ about 5%

there seems to be a lot of back-and-forth regarding whether or not draining a battery is healthy; i drain my iphone battery down to zero about once a month and the battery has been doing fine for two years . . . whether it would be doing just as well without the draining time is anyone's guess.

I have always been under the impression that lit-ion batteries do not need any kind of special care or break in. But since our phones estimate the charge, we should occasionally let the battery run out to reset the calibration in case it gets screwed up.

I don't think you need to worry about draining the battery till it's dead. My phone dies often and the battery is still kickin It's my understanding, that the purpose of draining the phone before you charge it is to calibrate what the OS says for charge remaining to the battery's actual charge.
Or something like that...

Hi all,
I have my sgs 2 since June and it's working pretty well apart from the battery drain which is very harmful in my daily life
I've recently flashed the Cognition 1.30 (last friday). Before that, my sgs was able to last the entire day before discharging with a moderate use (10-20 mn on games, few sms, 15 mn consulting mails, 1 hr on internet). Since i've flashed with the cognition Rom, the battery drain is really awesome!!!!!!
I fully charge the phone (switched off) then when i switch it on and the phone stays idle, after 1 hr or so, i've already lost almost 20%. When i'm on internet or playing games, the battery loss is approximatively of 1% per min.
I've made a full wipe and recalibrated my battery so normally it should at least last a day and thats not the case.
Could somebody help me or should i buy a new battery and test it ?
Because i relly like this rom and from others users, it has a good feedback concerning the battery use

When will Galaxy S6 battery begins to fail?

When will Galaxy S6 battery begins to fail? I just bought the phone and started to worry about battery life already. I am interesting in a 4200mah external battery case from mpj, is battery case convenient to use?

The typical estimated life of a Lithium-Ion battery is about two to three years or
300 to 500 charge cycles, whichever occurs first. One charge cycle is a period
of use from fully charged, to fully discharged, and fully recharged again. Use a
two to three year life expectancy for batteries that do not run through complete
charge cycles.
Rechargeable Lithium-Ion batteries have a limited life and will gradually lose
their capacity to hold a charge. This loss of capacity (aging) is irreversible. As
the battery loses capacity, the length of time it will power the product (run time)
decreases.

i sometimes fire up my 4-5 year old phones including my original DROID and kids play with them and they all still hold a charge. i have zero concerns of the battery lasting for the time period i will be relying on the S6 as my main device. my Note 3 which was my daily driver since release date until the S6 still holds the same charge it did almost 2 years ago.

My GS3 is on the original battery and it performed flawlessly for 2.5 years. Don't see how the GS6 could be any worse.

Charge and Discharge Cycles

How many charge/discharge cycles should I expect to get from my S6?
I got the phone in April, and since then I have used it for both business and private use.
I charge it overnight wirelessly, take it to work fully charged, then discharge and recharge it twice whilst at work (using the Samsung charger that came with it), then put it on charge for a 3rd time when I get home ready for the next day.
Fast forward 9 months and already I am seeing reduced battery life... Is this to be expected from 3 charge/discharge cycles per day, 6 days a week?
I've never seen this as a problem until now, as all my phones have either had removable batteries, or were only on 12 month contracts and were replaced before the battery became too worn.
Is it worth trying to get a battery replacement under the 12 month warranty before it runs out?

please clarify what you mean by "reduced battery life". Any phone will suffer reduced battery life to some degree after 9 months.
How low do you let the battery go before charging? Some say it's not good to constantly recharge when the battery is not low (above 50%)? Others say that doesn't apply to newer phones with better battery tech. I don't know.

I generally run it down to 15% when the battery warning comes on... Very rarely to 5% when the critical warning comes on.
When I take it off charge, after about half an hour of screen time, it's down to 80-85 already, then I can get about another 2 hours of heavy use and constant screen time before it's dead again.

Read somewhere reliable some time back that it's somewhere between 500-600 cycles before you see any degradation.. And I think there's something in the warranty which covers reduced battery life within 1st year provided you can prove it which basically means very rare!

New Battery?

OK, so I've had my SM-P900 for about year now.
Suddenly just this week I am noticing my battery is draining considerably faster than usual and is also taking longer to charge. I was using a custom rom but have now switched back to the default 5.02 version that I installed via Kies.
So after a year do I really need to purchase a new battery?
I keep most everything off all the time and really haven't changed anything or how I use it in quite a few months so was wondering if I actually have to break down and purchase a new battery already.
Cheers

Read the threat : Flickering screen to see how to adjust the tip of battery cable closer in order to make better contact before replace a new battery, within one year the battery should still be good.
If you see the same thing with new battery, probably the battery connector has cracked solder joints and needs to be re soldered, common problem of Samsung tablets, not just only this model.

Lithium-Ion batteries generally last between 300-500 full charge cycles before they start losing power. A year is.. way too soon.
Does it also take longer to charge when the device is turned off completely?
In general a drain increase is caused by a software issue, mobile data or a bug. (or heat/cold.) (The difference between mobile data on and off with a 4G connection is 100-0% in deep sleep in 2 days with LTE, and 80 days in airplane mode.)
Signs of a dying battery include random discharges (it suddenly loses 30-70%, it's at 100 when you unplug and suddenly drops to 30%, or it's dead, you plug it in and turn it back on and it suddenly has 50% charge), random reboots and the device just not turning on at all for no apparent reason.
While it'll loose capacity eventually, that usually doesn't negatively affect the charging speed. (If anything it charges faster because it reaches 100% sooner.)

So assuming that I have a dead battery, is there a good replacement battery out there?
I have tried replacement batteries in the past and have found only subpar batteries on the market.

I bought a new battery on Amazon : 26$
This one is an original battery so at this price you should order one.
And about flickering issue, yes you should resolder connectors or changing the battery might solve this issue too (it worked for me)
