NEED HELP:4800mAh Cameron Sino Battery and original 1620mAh battery problems!

[rosscruz08]

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.

[rosscruz08]

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?:confused:

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....:D

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.

[rosscruz08]

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.

Haven't we just been through this?

ooops!sorry my bad....
anyway thanks for your help.

[rosscruz08]

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.:D

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... :mad:

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:cool:

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?

[Final5k]

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:
