3250 mAh battery review (stock battery size)

spfraggle · Jul 4, 2012

Mugen is a quality product. They are proven batteries in that when you get one you know it'll work, last as long as it claims and won't harm your device. I've used them in the past and I can't fault them or their customer service. I had originally bought the 4500mah battery but a month after getting it they released the 5400mah battery for the same price and they were fine in doing an exchange for the new product. Certainly can't fault them on customer service or product quality.

Waiting to hear from people,

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160773578553#ht_4720wt_786 this the one to order if its a good battery?

Don't order 3250mAh, it only has ~2700mAh. I measured the capacity using this device:
http://www.eham.net/reviews/detail/1645?page=2
and it only has 2700mAh. I tried 4 types of batteries, the real highest capacity I found (real 3000mAh) is this one:
http://www.ebay.com/itm/260995972702?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

That's the one I'm using...

Did you get the 3250mAh battery yet ?, if so how did it stack up against the others you've purchased ?.

Yes, I did buy 3250 mAh, but it's a waste of money. I used it for a week and then measured the capacity by doing full discharge/charge/discharge cycle. Both charge and discharge cycles show only 2700mAh. It's still better than stock battery, but it's 20% less than the statet capacity. The highest capacity battery I found so far (standard size) is this one:

I just got a 3250 one from Amazon. It was already at 50% so I charged it up to full. I then went out on a hike where I had the GPS on. It gradually went down to 5% where the screen flickered and went black, and that's it!

It won't charge at all now, seems totally dead as the screen remains black when I plug it in. Left it in overnight and there isn't a squeak so not impressed.

If you bought it from Amazon you can easily return or exchange it, Amazon has pretty good customer service...

Trying to understand what you mean is

The 3250mAh battery only has 2700mAh,
but the 3000mAh is what it claims (the full 3000)

& also want to know if people who got this battery did follow instrutions:-

To get the best out of your battery please follow the instructions below:

1) When you receive your new battery, take it out of its packaging and insert it into your electronic device. Turn your device on and drain your battery until you’re left with 1 bar of power. Then charge your device for a minimum period of 12 hours. Your first charge cycle is very important, do not charge it before it is down to 1 bar.

2) After you have completed the initial charge, your battery should only be recharged once you drain it down to 1 bar of power and should be recharged for a minimum period of 6 hours for the battery to reach its full capacity. Ignore the phone telling you that the battery is full—this is normal but is not accurate.

3) Make sure that the contacts are clean.

This item also comes with a warranty, so if you experience any problems simply contact our diligent Customer Support team via email, live chat or telephone.

The battery came without any specific instruction for the first usage. When you buy a phone the only instructionis to fully charge it, and i'm not sure it is related to a battery capacity. All new batteries do not have memory effect, the charge/discharge sequence shouldn't matter. More importently, when battery voltage reaches 4.2V, it doesn't matter how long you keep "charging" it after that, since there is no charging current flowing into the battery. There is a protection circuitry to prevent overchsrging the battery, otherwise it will explode. So given instruction "to keep charging it" doesn't make any sense.

I measured battery capacities using specialized device, which discharges the battery with the constant current. Knowing the current, time to discharge and monitoring battery voltage gives you real battery capacity. Battery with the claimed 3250 mAh capacity discharges quicker than the battery with 3000 mAh capacity, from a fully charged state at 4.2 V to 3.4V. In an attempt to get better sales some companies simply lie to their customers...

toygixxer69 · Jul 14, 2012

The golden 3250mAh battery sucks big time. Drained it & fully charged (more than 10 hours each time) to use it 3 cycles already, and the results are the same. It has shorter life than my stock battery. So i'm just using it as a back up battery now.
So, same your money guys.

zilchie · Jul 14, 2012

hi there, new guy here (first post!)

im a bit puzzled by the mixed comments here because i personally bought the 3250 mah battery from ebay and got GREAT results

on my stock samsung battery if i fully charge it before sleep, the next day it WILL NOT last the whole day on my normal usage - semi heavy usage with a lot of browsers and facebook, music, and whatsapp

on the 3250 mah battery it lasts just fine - i checked this again and again as i was always paranoid about using OEM batteries (especially due to that news of the galaxy s3 exploding - which i later found out that the idiot was putting it in a microwave or something)

i was not able to confirm the actual capacity of the battery, even though battery stats app shows it is 3250 (is that even accurate?)

but one thing for sure is i know it does lasts longer than my stock battery - just want to add this in

vipfreak · Jul 16, 2012

The problem isn't that it last the problem is that down the road more long term it doesn't keep it's full charge as long as when you first got the batt. If they've improved this since the last time I owned one (EVO) then I'll be more confident about trying one again, but till then no thanks...

krazman325 · Jul 17, 2012

Hey all you nattering nabobs of negativism!

I have been using the 3250 mAH battery for several months. It lasts me an entire day of fairly heavy usage, while the stock battery fell about 2 hours short of a full day. I have seen very little degredation in performance in the few months I have been using it. This battery was an excellent buy for ME at $11. I have no regrets and I have the stock as a spare! I would make this purchase again without any hesitation.

I have a 3250 mAh battery too and I'm very happy with it. I usually charge every other day instead of every day with stock.

It is not the "Japan made„ one but one I bought from a Hong Kong retailer.

This is exactly it. The only thing that I haven't really checked is the maximum screen on time, since over two days I still get about 3h screen on, but I sync quite a few services.

I hope you'll enjoy your new battery as much as I do.

I tested almost all batteries except mugen or other double sized or external batteries, only stock size ones. I can tell you that 3030 and 3500 "japan designed" batteries are extremely disappointing (I try to avoid being insulting). They were cheap and as I can afford an extra $20 I tried them. I will make this even more clear: do not buy those batteries, they are fake.

The 3250 sold by efreeport99 does it for me as I reported earlier. The only drawback that I did not mention but that may be due to not having reset battery stats: The battery is sometimes reported as "charging" even if I keep it away from a charger (I have been seeing that in battery drain app).

I previously used Anker 2700. They are good batteries with a little extra juice than stock. I keep them as spare now.

Thanks for the reply man

I emailed mugen and sedeio to get a review unit to post here to run it through a battery of tests but no reply yet ... the manufacturer of fake Chinese batteries get better press on these boards

So 3250 mAh battery from "efreeport99" arrived today. Battery Monitor showed it as 2500mAh. Cleared battery stats and entered the value normally within the app. Will be testing it this week to see how it goes ! :good:

Squadra156 · Jul 31, 2012

After reading for ages trough this topic I also decided to buy one..!
Paid €15,90 for the battery incl shipping from Hong Kong to the Netherlands.

Do you have to first charge a new battery for 4 or 8 hours ? My 3250 mAh battery from "efreeport99" also arriving soon. I keep hearing rumors that the battery will explodes or whatever. Hope the new battery is safe.

It came with nearly 60% charge, though I did charge it till android notified that the charge was complete.
Been using it since it arrived and seems a bit worse than the stock battery. :/
Maybe it needs some charge discharge cycles.
