Hi guys,
I want to replace the battery of my 9900 and searched on ebay and found some with 2600mA for about 13$.
I sent a message to the seller and he said that it is that slim as the original one and can fit without a special back door. (thats what he said)
Have you tried one of those?
Are they safe(non oem)? Thanks in advance

[Berry_Pink]

guarentee they arent the stated mah and some people have said gold batteries have fried their phones

i have a 1900mah one from ebay that works perfectly and lasts about 2days

what do you mean "heve fried their phones". can you send me the link of that battery on ebay or just the name it is listed? and do you use a special back cover for that battery or just fits like the original one? thanks

[Berry_Pink]

it fits like the original no special back needed

A lot of batteries that are supposedly bigger in mah, aren't really made for BlackBerry. They either burn up your phone like stated above or they last just as long or less then the original JM-1 battery..

Mugen is a good brand! They have a 1500 mah battery which is the same size as the stock JM-1 and I have heard nice reviews about it. People were getting up to 20% more usage out of it!

Amazon.com: mugen battery 1500 mah

mugen coasts about 50$ including shipping coasts and i think doesnt worth the money for a 20%. my battery lasts about 10 hours(no heavy useage), so 12 hours is the same for me....
maybe i have a dead battery because i bought the 9900 used. thanks all

[Berry_Pink]

10 hours isnt too bad on an original battery, are you using your phone on all the minimum settings and setting your apps to refresh manually or once every 12 hours? have you got battery saving mode switched on, have you switched OS's to a hybrid or the latest leaked/official?

with the battery i linked to plus a hybrid os i get an average drain rate of 0.8%-3%(0-full usage) but it takes around a week for the battery to settle

[anon(4166778)]

The Mugen battery is the only other battery maker besides the stock that I have seen that is legit, but also me personally I wouldn't buy a battery for $50! Might as well just buy another JM-1 stock for cheap on Amazon and just switch out 2 batteries.

10 hours is decent for a days use. That's all your really need until you get back home. That's like a work day right there. But it's all about discipline. Having the settings right and making sure apps aren't draining your battery. Also having the latest OS will help! Because the earlier versions of 7.1 are not as efficient as the newer versions..

I'll sell you my Mugen for a cheaper price. I don't use it and found it 10% better.

[Biulet]

I've tried one of 1500mah (not the Mugen one) and I found that the 10-15% more that it gives its not enough for me.

I bought a "Gold 2400mah battery" from Ebay and IT IS NOT TRUE that is 2400mah. Maybe it is like to original one or a 1500mah but sure it is not a 2400mah!

blackberry9360user, do you recommend me this 1900mah battery? It really lasts more than the 1500mah? Thanks in advance.

Cheers from Barcelona! ;-)

i havent tried a 1500mah mugen one, i just bought that one a month ago and ive had great results. Like i said i get 2 days usage from it and about 12 hours maximum usage with phone calls, music playing f,or hours and messaging. im also running a hybrid os with it so i reccommend updating too as im not sure if youd see any amazing improvements on a normal os. maybe i just got a good battery im not sure if they all work and it depends on how you use your phone so no one really gets the same results but ive attached some screenshots of the battery monitoring app to prove how long it lasts idle and how long on light/medium usage.

[Biulet]

Thanks for your answer! I will take a look if I can install an Hybrid OS in my 9900.

By the way, do you think the 1900mah is worth buying even with the official OS?

Cheers from Barcelona! ;-)

[Berry_Pink]

it cant hurt to try it for �5 lol, if you need help installing a hybrid ill be glad to help

[Biulet]

Thanks again blackberry9360 user! I will try the battery you showed in the link.

Also, I will install an Hybrid OS to my Bold when I have time.

I think that with an official OS is impossible to get a discharging rate of 0.8%/hour! I'm between 6%-12%/hour.

yes ive got hybrid, battery saving mode on and always 2g. one thing i miss is how to set apps to refresh manually or every 12 hours as you said. thanks

[Berry_Pink]

im not sure about all apps but those with feeds etc or ones that auto update should have a settings/options icon when you press the blackberry key inside the app - facebook for example: enter facebook press the bb key and select options then scroll right down till it says refresh options, refresh messages set the news feed to never refresh as you can refresh it manually from the menu if you ever want to see the latest feed, do you always close out your apps after you finish using them?

[westiewanderer]

Im running the 1500 mah MUGEN battery and it DEF gives me 10-15 percent better even on the stock OS.....I wouldnt trust too many more battery companies as they Usually just wrap the original 1230 mah in dif packaging! LOL Good luck, I hope your finding the answers you need to get that coveted battery life!! I hope Blackberry stays true to its minimal battery requirements in BB10!!

[eve6er69]

i only personally trust 2 companies for batteries and thats seidio and rim. thats just me but i have 2jm1 batteries and also the seidio 3000mah battery. the seidio does not fit into the oem door. thats why they give you an additional battery door for it.

A week ago I received the battery given by Berry_Pink and it works great! It is definetly more than a 1250mha (I don't know if it should be 1900 or 1500mha) but I'm sure it gives better battery performance.

Also, I tryed one with a Bold9790 and now the battery lasts more than a 20%! So it works even better with this model.

Thanks Berry_Pink for you advise!
