Hi I was thinking of getting these 2600mAh batteries http://www.amazon.co.uk/gp/aw/d/B007AA1E3K/ref=mp_s_a_1?qid=1337533622&sr=8-1 the stock baterry is 2500mAh will these work okay?
they might "work" but i doubt they will last as long as the stock battery
also the external charger may not detect when battery is full so dont leave one on there for days, just an hour or two for a boost
Might influence your buying descision;

Hello Guys!
I own a HTC ELF (64mb) ´for almost a year now and about 1 month ago a malfunction happend. My guarantee did repair it but it tooked over 4 weeks until i got my phone back... They changed almost the whole phone but they leaved the old battery in. 1100mA Li-ion over 4 weeks uncharged --> not good!
So unforunalty my battery life is shorter now It needs almost 5h until it charges full but it has not even 25% of the lifetime it had before!
Its really desperating because i cant do anything with my phone without carring the charge cable with me. Im sick of beeing afraid that my charge dies immediately so im looking for a new one. Ebay has some pretty nice offers like 2400mA charge but i dont like the bigger size.
There are 2 options im considering with:
First is to buy a "normal" 1100mA or
Get a "external" battery with 3000 or even 4400mA of giantical power! Only Negative point about is the fact to carry a special charge with ya but i think its not that bad as my idea looks
look here for a 3000 version
Or even 4400 !
So what do you guys think about my idea? What is better? To buy a new battery or leave the old and get a external charge with 4 time more power?
it's always a good idea to buy a second battery, but i dont recommend you to use an external power supply that has 3 or 4 times than the original one.
first of all im sorry if this issue seems to be redundant to all....
im a bit confused to some of the post on this forum regarding this issue...
(so please bear with me...especially to the mods out there)
i do have this battery and it seems that it wont even last for atleast a day...
is this normal for this brand of battery or 4800mAh battery?
how long is the normal standby time for 4800mAh battery?
i also have an original 1620mAh battery and it even last longer than my 4800mAh battery..
can anyone here help me on what to do?
is there anyone in here can prove that 3200 or 1620 is much much better than 4800?
and one more question...i also have a 2 spare 1620mAh battery....
one of it turns off at 75% the other at 21%....
i've tried resetting them both but no of luck..still the same..
is there any other possible way for me to use them and drain them up to 0% or atleast 10%?
thanks in advance!
3200 will last twice as long as 1620; 4800 three times.
However, this is given they are all the same manufacturer. Some batteries are better than others. Cheap eBay batteries are known to give problems - however I have had good as well as bad one's from eBay.
Also, batteries will wear out after a while - I think suggested time is a year or two.
I have four 1620's which last from 50 minutes to 3 hours (constant useage with backlight on). My 3200 lasts 6 hours.
I find that whichever (fully charged) battery is in Uni when I upgrade ROM, will give accurate reading. The reading becomes inaccuate (turning off a x%) when I swap for different battery.
ROM Upgrade & battery
so your saying that when i upgrade or change rom..
1. the battery should be at 100% charge..?
2. and the battery that i used when upgrading should be the one to be used until it drains to 0%? coz when i replace the battery thats the time it will shut off at X%?
is my understanding correct?
if i may ask...what brand of battery would you recommend for a 4800mAh?
and would you recommend 4800mAh?
ive seen DUKE NUKEM's post..he's selling batteries right?im planning to buy 2 pcs of 4800mAh....but the problem is i dont have a PAYPAL account and im a bit confused coz some say 3200 is much better than 4800..and some say 1620 is the best...
thanks for your help sir jonny....
Yes, you are correct.
I don't have a 4800, so can't comment.
Anyone else got a recommendation?
The main reason that people prefer one battery over another is due to the size. Most people seem to like the 1600 because the Universal is fat enough without having a huge battery sticking out the back! Other people may be biased toward a certain capacity because they bought a duff battery.
Personally I'll use a 1600 and carry a spare sometimes... unless I know I'm going to need juice (for a plane trip etc) and I'll stick in my 3200.
what to do on batteries shutting off at x%?
sir jonny do you know a way on how to correct those batteries that shuts off at x%?
coz what im doing is
1.charge the battery to full
2.put an adhesive tape to cover the second connector of the battery
3.then drain the battery using my UNI or using 3 LEDs...
4.charge the battery again to full
the problem is that it still shuts off at x%...
some claims that this corrects the problem..
am i doing the right way or is there any possible way?
ive seen some threads regarding this issue but in my case it dont work..
ive got 3 pcs of 1620mAh with this problem..
thanks again for your help...
Did you charge it with your original charger? If not, you can't get 4800 mah.

im always using the original charger....but if your talking about the initial charging prior to shipping of the battery...i cant answer that because i bought that battery from a friend...and it is a second hand battery..but he told me that he just used the battery once and havent asked about what charger he used.
I have done some efforts regarding battery capacity measurement Just lookup this thread: http://forum.xda-developers.com/showthread.php?p=5558383#post5558383
I would suggest stay away from the Sino Cameron batts. They simply suck. I have one 1650 and another 4800. Both not very up to stretch, especially the 4800. By all means it does NOT last three times as the standard batt. I'd say perhaps just about two times in reality. Perhaps not. I just keep seeing the batt level dropping fast. Plus the build quality is a real issue. Somehow the 4800 gets too fat and the batt cover cannot completely fit in the slot. Three times the size but just a little power boost. It's cheap, but now I regret having wasting money on them...
Then I switched to Momax. It's just a standard 1500. But it shines! Battery drains pretty slowly and stably (no sudden dropping). It's a bit more expensive than those crappy Camerons, yet it's worth the extra dollars.
Yes, right
It´s always better to go for the original one

If you want a good battery for your Universal, I will suggest you to buy a 3200 mAh battery from ebay, it's the best
Which brand of 3200 batt do you recommend?
I have 2 similar 3200mah batteries but to speak frankly, I used them mainly at home and when I go out I take 2 1620mah batteries with me. The 3200mah is simply too huge & heavy - since the Uni is a big phone, people may find it funny if they see the overal size especially when you are putting it near your cheek when receiving/making calls! You can check this link - the seller also sells cheap 1620mah:

No bro!! Cameron Sino is garbage batery I did buy the samew batery and dont worksmy uni works like a stove and the batery drains faster.
I purchased the Sieidio Battery 1750mAh on Amazon about a month ago. This battery is not worth the money at all. If you want an extra battery then I suggest buying an OEM battery.
I might be wrong but I think this battery actually goes down faster than the one that came with the phone. My biggest problem with this battery is that it does not fit properly in the phone. It can just be set down or place in my pocket and that is enough to make the phone.
DON'T wast you money on this battery

I don't even understand your review, but I guess I do understand you are being negative.
But this battery works way better than the stock battery that came with my EVO. It ****s on the stock battery. Diarrhea.
Maybe it's just because I bought it for $50 from Best Buy. What a bargain!

Sounds like too much for a 1750 battery. I'd rather just go all out and get the 3500

I got two 1800mAh batteries for about $30, and experienced the same thing. After awhile though, I realized that you have to do a few things to get better battery life.
1) Charge the battery to full while the phone is on.
2) Unplug and plug back in to verify that the phone is fully charged (green led)
3) Turn the phone off
4) Unplug, plug in, and wait for a green led
5) Repeat that 5-10 times
6) Then while still plugged in, reboot into Recovery and wipe the battery stats via the advanced menu.
7) Reboot, and use your phone as you normally would.
This may sound like alot, but it really only take about 5 mins. Even after wipe, it will still take about 5 full discharges to reap the better battery life. Hope this helps!
I think its just luck of the draw on aftermarket batteries (the cheap ones at least)
I have heard good and bad on ALL of them.
I got the Chichitec/htcexpress 1800 batteries with charger. Came in the other day and I couldn't be happier. 14 hours on initial charge, that's unheard of for me. On my stock battery I had to keep the phone plugged in most of the day at work just to still have juice by the time I got home. And supposedly these things start acting even better after a few charge cycles.
(Fits with stock battery door too)
But for every person that has a good experience with any of these companies, there's someone else with a horror story.

Could have told you that before you bought it, ratings by aftermarket reputable companies are close and never accurate...if they rate it at 1750, it's probably 1500-1650... The stock is 1500 so yes you wasted your money. Now on the other hand, the 3500 is the best investment anyone could ever make....
It's been proven long ago seidio over rates their batteries. The "1750" is actually just under 1500, so less capacity then the stock battery.

just terribad in my opinion, gonna stick to my seidio 3500. rather have the size and life than a small size and a measly bump from the 1750mah battery
They rated it less than a 1500 stock battery.
Key with extended batteries is that you actually have to charge them longer than your phone indicates.
Example: I phone said it was fully charged at 3:26am in the morning. Yet it continue to charge until at least 6:45am before it was constant. Granted I am using an SBC kernel but even without, you need to let it charge the night. Don't let the green light fool you. It takes a few extra hours to charge even if the led light is green!
You should just about fully drain your battery and then let it charge overnight. If you aren't on an SBC kernel you may actually want to charge your phone while it's off so that the battery dictates the charge.
You should also wipe your battery stats once the phone is fully charged.
Try that and see if it works for you. I know that I was getting great battery life even on the stock battery. I play "Word With friends" (at least 15 matches running) a lot (at least 15 matches running concurrently) and this game actually drains battery. I still got through the day fine though I also carry a Touch Pro 2 and having the batteries that are the same size allows me to swap when needed.
I have the 2650mah one from sprint and my 3500mah seidio coming in the mail tomorrow. I'll probably write a review for it later. Note, On my 2650mah, it's already on its 12th hour and I was was playing WWF, surfing the web, made several calls and it's still at 77%. I will leave it off the charger tonight and see how it fairs tomorrow.
Good Luck!
I have tested these and if they do last longer then stock, it is only like maybe 20 mins. I have an external charger as well as running the SBC kernel to get a complete charge. I have the sprint 2600 battery as well and love it. Not many cases for it but I have modified a sedio rugged and ballistic to work with it. I let my wife use it for a few days in her evo and had to fight to get it back from her.

Hello folks..
I have a HTC Desire CDMA and I bought a Extended battery (3500 mAh to be exact) and this battery lasts just about as long as my normal battery does. It is thick enough to be 3 of my regular batteries, and it is alot heavier, so i know it wasnt a scam, plus there was good reviews... but, The only difference that I get with this extended battery, is that it stays at 100% for about 3 hours, and then starts booming down the charts on battery level.. I mean, i normally have about 25% at the end of the day with this extended battery, but i figure that it should atleast last 2 days on a full charge.... with it being 3500 mAh.. I mean, wow... Can someone help me? Im using a trusted stable battery saving kernel and rom.. so I know that's not the problem..
bump.........?

Do you have a custom rom? Try to download SpareParts from the market and unplug the charger when it says "charged". For my Samsung i5500 and a cyanogen rom the phone says "charged" a lot of time before the real charge...i think that the batterystats file isn't calibrated on your new battery, and so it says charged before...if you have a custom rom i think it's useful (if not necessary) to do a battery ricalibration (i.e charge the phone until the 100% then wipe the battery stats via recovery and then let the phone discharge until the 0%)
I don't know if this will help you, i hope!
I think
When i go back home tomorrow and pick up my extended battery, i will try this. thanks.
edit: yes i have a custom rom. it's oxygen.
I've read a few mixed opinions on draining the battery fully to ensure maximum charge potential or whatever. Can someone tell me what to do now that I have the dang things?
Also, I bought two, so if anyone wants to buy one send me a PM.
uhh full drain on a li-ion is BAD! just charge em and use em ..
I've read to get the best long term life out of your battery to try and keep it between 50% and 90%. No need to ever fully discharge or charge.

I have been running mine for about 4 months now and its great. I can actually get a full day of heavy usage without it being dead before I get home.
My stock battery usually die in middle of the day if I use it frequently with wifi on all the time
Have been wanting to buy a new one. Any suggestion?
I bought two also, and they came with a cool external charger [for the batteries only]
I recommend keeping the 2nd battery, and always have one charged and ready to go. Great for long trips, as the gps seems to be a huge battery pig.
I'm very pleased with these batteries.

I have them also but im not sure if you noticed that on the side of the wall charger it has a usb and micro usb to plug the phone in and be able to charge with the battery in the phone.
