Mugen powerbattery 1800mah for legend full review

Hei,
Ever since i saw this thread, I was considering a better battery for my legend.
To begin with the stock battery (Standard HTC battery) that came with the phone.
1. It used to last me for 2 hrs 10mins of voice call
2. If GPS was on it takes about 25mins to fully drain from about 95%
3. between 80to40% whenever screen was switched on, phone used to heat up.
4. At times (lately) even when the phone was in stand by in my pocket, it used to heat up so badly, i had to refrain from keeping the phone in my pocket. It actually felt like a "hotpack" in my pocket.
Phone is just perfect except for the retarded battery that comes with it. Whats the use an awesome phone if it you cant go through a day of light to moderate usage without requiring a charge?
So i decided to try out the mugen power batter. I love my legend, so even though battery was a bit pricey about INR.2,153.00 (USD46.95) (after shipping). I ordered a mugen battery 1800mah from their official website on 8th Nov. They took about 14 days to ship it to India from Hongkong (3 days waiting as batteries were out of stock).
Received it a week back. and currently i am running the 4th recharge cycle.
Immediately installed the battery on receiving it. (Couldn't wait!!)
The battery came with instructions to fully charge the battery (even after its fully charged as indicated by the green LED on phone) for 10-12 hrs for each cycle and nearly drain the battery before charging it again. (I took it to 5% each time, charged for a minimum of 11 hrs)
The fit
I was dead scared seeing the comments in this thread. But the battery was a perfect fit, infact the same fit as the stock battery. It would directly slide out without any poking / fingering
Tip - There is a small red plastic stick in the battery compartment to assist in battery removal. I dont have to use it though
The following are the actual statistics i have written down after each cycle. (Help me post a screen shot pls)
Recharge cycle 1
1st charge for 12hrs continuoesly
Voice calls 29% - 45min 44 sec
wifi 30% - 7 hrs 22min
Display 27% - 2hrs 12min (full brightness for 1hr)
Mpas 8% - GPS -23min, data 10mb
cell standby 4% - 7hrs 22min
phone idle - 2% - 5hrs 12mins
Total 7hrs 22mins from 100% to 6%.
Dint record the 2nd cycle, but was difficult to drain the battery in the next 13 hrs, had to switch on GPS + music on for 30mins on speakers + torch app with about 80% brightness for 1 hr to drain it before 11pm the next day.
I wanted to charge battery for atleast 10 hrs before leaving for office
Recharge cycle 3 Unbelievable!!!
3rd charge for 11hrs
Voice calls 12% - 1 hr 15min 12 sec
wifi + bluetooth 44% - 37 hrs 12min (dint turnoff bluetooth/wifi) transferred about 153mb in this cycle
Display 17% - 3hrs 12min (played angry birds for 1hr!!)
Mpas 13% - GPS -14 hrs 12min, data 43mb
cell standby 9% - 7hrs 22min
phone idle - 5% - 5hrs 12mins
Total 37hrs 31mins from 100% to 4%.
As you could see there was a drastic increase in battery performance after the 3rd recharge.
------------
Note - I am using juice defender (free version) + the phone is on strictly GSM only mode. (Exhausted my monthly data quota on 3g )
Currently I am charging it for the 4th time. Will post the final results again.
Also as froyo users are posting better battery performance, expect even more longevity of the battery once i receive my OTA (damn ever eluding update)
Conclusion - Definitely its a drastic improvement from the stock battery and the best part is it resolves the only problem i had with my legend, heating of the phone for no reason!
Makes me wonder why legend doesn't come with such a battery on default purchase.
Thanks Mugen for such a great battery
Do drop your comments and suggestions below or any standard benchmarking tools that i can use ...

Review part 2
< Reserving for 4th, 5th and final cycle >

Heating up is unusual with legend under normal usage, are you sure it has to do with the stock battery?
Some people did report problems with juice defender, your case may be different though.
Gotta say mugen battery was very lasting initially if you follow their instructions properly, but after using it for couple of months I don't think iam getting that same performance, its much less.. though still better than the stock one.
My mugen fits lil tighter than the stock one, its hard to get it out without that red lever. Iam kinda surprised about yours being the same fit as stock one. Dunno if they changed anything.

No heating issues at all after replacing the stock battery with the Mugen one. Havent changed / installed any new apps / software for the past 2 weeks. 1 week with the new battery.
So i can confidently say the stock battery is the culprit.

Hope mine gives the same performance at a later stage as well. Can it be that you got used to the longer battery life and dont realize it now?

I dont know if they have made any changes to the battery. My Mugen slides right out of the slot on tilting the phone after opening the case just like the stock battery!

It could be that, but iam sure it doesnt last as long as it was initially.. but still better than the stock one for sure.

Mine doesnt slide right out like the stock battery, it does need lil effort. (ie. the red lever) May be they made some changes after selling many pieces ?

I've experienced the same short life when charging through USB, but when I use the wall charger, it lasts much longer.

Going to bite the bullet & try out one of these, just awaiting the money to be put in my PayPal account.

Battery life?

Hi all lucky owners of lg optimus 2x,
I want to ask you a question about battery life of optimus 2x . Is it really better than single cored ones or same, i m not expecting better life really
Sent from my HTC Desire using XDA App

There's a good review in the optimus 2x forum:
http://www.optimus2x.net/index.php?topic=156.0
Conclusion:
30mn YouTube HD (wifi)LG Optimus 2X: 9% battery​Google Nexus S: 7% battery​30mn Neocore (3D graphics)LG Optimus 2X: 12% battery @ 74FPS​ Google Nexus S: 9% battery @ 54FPS​8hrs of stand-by LG Optimus 2X: 2% battery​ Google Nexus S: 3% battery​

Wow, quite good !!!!!!!!!!!!!!!!!!!!!

I think that test is a bit flawed... PaulOBrien reported that the Nexus S exaggerates it's battery % quite seriously...

pokerfake
You are used o2x. What can you said about battery life of subj? On sleep mode? On used mode?

Here is an interesting test of battery life of the lg o2x.
htt p://anandtech.com/show/4144/lg-optimus-2x-nvidia-tegra-2-review-the-first-dual-core-smartphone/15

my battery life blows :/

Well, mine has a pretty good battery....you know now I have time, so I just keep playing with it all day, so with auto-brightness and WiFi always on, playing pretty much all-day I got through 1 day without my charger. Without wifi and less playing I think 2-3 days could be easily achieved.

I am using V10d rom unrooted.
It happended several times now. I need to change SIM cards often as I travelled to different areas during my work. Before I pull out the battery,it is at 50%. After I change SIM card and put back the battery, it drop to less than 17%. It takes me less than a minute to change the SIM card. What happened to the battery??

Use juicedefender

I managed to get 3 days+ out of it under average use. Could probably easily manage 4+ with setCPU or something underclocking the processor and turning off data, etc.

i'd like to know too. My battery life sucks. Barely make it through a day now. On MCR FR17..

This is one of many threads about this.. But i'll respond anyway.
I had same issue, after some tests, i found out its GSM part of phone thats draining the juice. With airplane mode on it was about 3% in 8h. I was on BlazingDragon, with some apps, normal phone use It lasted 24h on standby without any use, no more.
Yesterday, i tried to flash (lastest for central europe) stock firmware, including baseband, simply i got the phone into factory state. And well, during night with data off it was 1% (yes, you are reading it right, i woke up with phone on 99%), now 10h later with lighter usage (some mp3, not much, a little of tapatalk, gmail push on) i'm at 78%.
I dont have any software except tapatalk installed atm. Dont think my problem with with BlazingDragon rom thou, i suspect some application caused it, but dunno which one
I think it will last 2 days with current usage, and several days with data disabled (using it as plain old phone only for calls )
PS: I dont use any JuiceDefender etc..

Iam using slicks rom, if i only write sms and surf sometimes, i have to charge every third day, but if i playing THD games, i have to charge after 3-4 hours

+1
the stand by time is really nice but gaming sucks out everything from my battery

Other than the battery drain during standby, my current observation is that, say if my battery was at 50% before I pull out the battery (say if I need to change SIM card), after I changed SIM and put the battery within one minute, it suddenly drops to less than 17%. Why the battery loss 33% in no time?
People keep saying that the phone can last a week if it is on airplane mode, or by turning off data 3 days, but then why we need a smartphone of such build?
Has anyone compare the other dual core or tegra2 phones in the market how they perform battery life? Do they have such awful battery drain standby? LG said the battery drain was due to incompatibility of tegra2 and android 2.2. Why sell the phone in the first place? This problem starts from day 1. LG no QC or just want hiding this problem from customer?

it looks like a calibration problem. Either 50% or 17% reading was false.

Just did two full days after reflash with MCR.

How would you compare battery One X vs O4X?

Anyone has any opinion about this? A friend asked me to trade phones (One X for the Optimus 4X) cause he likes more the LG. I also like more he LG but the 1800mAh battery of the One X scares me, although I've read that it performs better than the battery on the LG.
Which phone has a better all around battery usage?
I ve used root freezer and froze many system apps, possibly that helps. With wi-fi constantly on for example today (although no browsing) just notifications from Facebook, I have 60% battery left ~14h on battery.
What makes me say WOW, is that I see 2% battery used on the display (41minutes on) and when I see similar screenshots of the One X the screen is 60% while the standby is at is 20%. Does the screen of the One X consume that much battery??

well, if u are familier with custom kernels, ull understand that they provide more performance ans battery. and also custom roms make a huge difference. for hox users, overnight drain is within 2 percent, amd most of the time 0 percent drain. and usually battery life is arouns 20 hours standby with 3 hours screenon. and that includes over half an hour gaming, calls, texts, and tapatalk. heck, i even tango for half an hour

..it's very easy to set up the lg 4x to draw around 7-8% a day on standby/sms couple of e-mail checks/some wifi-streaming use (turn off 3g, etc.). I had nowhere near that on the onex I tried when using the same settings. Basically you need to wipe the rom clean of extraware before you're going to see acceptable level of idle-activity.
Not sure where the entire thing about battery life comes from. Had the 4x last 4 hours of Max Payne. That's.. more than any other phone with the same hardware. By a good margin. As in 1-2 hours longer.. So ..
Honestly would have sold the 4x and gone back to my symbian phone if I had to charge the thing every day.

i dont have One X.. but maybe that one is better in battery life..
because LGO4X's battery drains quickly here

Mpj Optimus 4x p880 slim battery a little higher than stock

I poked around looking for battery of LG Optimus 4x p880 and there are some with same dimension but higher capacity. The one I bought from mpj required my phone drained till it died and then charge to 100% (repeat several times). It REALLY a little bigger than my stock! Some days I get 40+ hrs of use out of my device. Surely it has shorter life as they have claimed, but I don't care. All I know it has getting better.

Thats nice, where can we find it? How much it cost you? Still happy with it? Regards

sounds good, where do you get the part

Normal LG 2X battery life

Have been used LG 2X since the first launch date and it was fine until when the phone getting hot and battery life draining fast quickly. It was about only 4-6 hrs from full charge. I have been checked to see what was running but nothing weird.
Normally how long does the battery run after says 3 years of using it?

Don't know. I can only tell that after changing mine .75 years ago, suddenly battery life improved with a factor 3; now I have +-24 hours.
So, it might be time to buy a new battery - I definitely recommend LG stock battery (low price compared to changing phone).

I've also 3 years old optimus 2x and battery was horrible. It was on 10% after some 6h of usage so I bought from ebay 3 different batteries.
One was from Hong Kong, 3500 mAh and battery dried to 10% in about 2 days. I could finally use my phone without worries but that battery is fat and my phone looked really ugly. Afther that I've bought Onyx battery with 1400 mAh. Battery is real ****. After 4-5h of usage it was completely out and afther that I've found on ebay battery from china with 2450 mAh (I recommend you that one). I can use my phone for abut 8h, also I've found some app on google play that actually improved my battery life so I can use that battery with 2450 mAh one full day without worries. Here is the link https://play.google.com/store/apps/details?id=com.gejos.android.batterysaver I really recommend you this app. First one that really worked for me.
If you've any questions P.M. me. Good luck

Try flashing a lite rom, I suggest tonyp's PA ROM, or install greenify

I'd planning to buy a new battery for my SU 660, so the higher the mAh is the longer the bat life is? Coz mine is 1500mAh

I have had my last phone for nearly 3 years and the battery life is horrible. Why not try a new battery?

Greenify is you friend.

Mates, when I was using cm10, 11, my battery lasted for about 12 hours, but when I downgraded to gb, the battery lasts for more than 2 days, so the os gives many thoughts to consideration.

3500 mah battery 10€ and gives you alot of juice. but the stand by of this phone is bad.. i can beter use it somethings the let is sleep. no wake locks. just bad... my baseband is good normaly. bref i dont mind my phone is fat. it gives me battery i want. so yeah

I've used my O2X for almost 3 years now and original stock battery still gives me 16-24h battery life with normal everyday usage. Well, i have two stock batteries and swap them time by time but still. No fancy battery saving apps, but i turn wi-fi/data off manually quite often.
Heavy usage can hold max 4 hours on one battery (screen on all the time, GPS on, multitasking)

Normal withstand 24 hours.
