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.

great review..pavan
I would like the link to official page exactly where u did shop and also the detailed battery product number which we have to select...I am from Mumbai..

standby battery drain?

Sooo. I have had my Optimus 2X for 2 days now. I charged the phone fullt before goint to bed and left wifi on. (should turn off when phone sleeps)
The first night i lost about 3% of the battery. Great....
But... The second night i lost 42%!!!
I have been trying to investigate the issue and after some digging with spare parts i found out the wifi was on all the time the second night... Also for some reason car home allways runs in the background (starts at boot and restarts if killed) and spare parts claims car home uses the phone sensors 100% of the time.
Anyone else having battery draining issues?
Im going to charge 100% again tonight and run with no installed user apps. If the problem persists i try and freez some of the loads of sys apps that run in the background all the time.

I also noticed some battery drain on mine but not over 40%... its more like 20%. The battery really disappoints me anyway. I have to recharge two or three times a day?l maybe thr battery needs to get trained over time, I hope...
You found a solution yet?

My battery already holds up alot better now, then when i got the phone four days ago.
About 60-70% left after a 14 hour day with some surfing, benching and calling/texting. Much better then my Desire on stock ROM, but still nowhere near the Desire on custom ROM.
Looking forward to some community goodness
BTW, removing carhome.apk seems to make quite the difference.

Same here

Quick question about best used on the battery ...
Should we dry the battery to 0 for the first cycle ?
Or only to 20% ?
Is it bad if we start to charge the phone whent the battery is at 60% ?

On the contrary:
modern Li-Ion batteries don't like it if you discharge them to a minimum. Moreover they don't have the memory effect that you seem concerned about.
In a nutshell: Charge your phone whenever you can, at any charge level. Your battery will thank you.
On the first few charges though, you should always charge to 100% to help the battery gain her full efficiency

hey thx about those informations
but then i'm concerned about people saying stuff like "have been doing 3 life circle" for me it does mean they put the battery dry clean ...

Went to bed with 64% charge on the battery. When I woke up (8 hours later), still 64%.

I think it might be because I froze all the applications I didn't need.

Been really impressed by this phone's battery. Definitely better than everything htc has to offer.

What's your usage like?

Hmm... My phone last for 6 hours before drained... Had it for a week now... Takes about 2 hours to fully charge up again..
I even hardreset, turned of wifi etc... but alas, 6 hours and it was out of power again...
And that was just by being in standby.
If I actually use the phone, I can see the percentages going down from 100 - 0 in no time..

[Q] Dying battery?

I bought my stone in April 2010. Since about 3 weeks ago, my phone have been suffering from sudden battery level drops.
When the phone is being discharged, the battery level drops from about 78% to 63% suddenly. Then when the battery level reaches about 45%, it once again drops to 19% suddenly.
When being charged, the battery level leaps from about 19% to 62%, then jump to around 78% and starting increase incrementally until 100%.
The whole charging procedure only takes about half an hour. Does this indicate that the battery is dying?

Sounds right about it.

You should just buy a new battery. I bought mine for literally around $2-$3 from amazon.com. I just got my new battery in today, and it's working pretty well!

could be a rom problem.. try a different rom. if the problem stays, time to buy a new battery

it seemed that i once experenced the same situation u've just had.
i recommand u to flash a different rom before u purchase a new battery.

I have the same problem. i would suggest a battery replacement.

Battery Degrading?

Hi, Lately I've noticed my battery draining very fast. Like 50% in 4 hours. So I installed accubattery to further see why. After a while it states my battery capacity has dropped to 80%. I've been experiencing miserable battery backup ever since. Do I need to change my battery?

When did u buy it and how often do you charge it?

Hi, I am also experiencing bad battery life, I'm on OOS 5.0.6 without root (stock kernel). Last month I was still on Nougat OOS and battery was fine, so I would go ahead and guess oreo is eating a lot of battery, also you can try and switch to 2G network, I was on 4G and mobile signal was not good and drain was higher then when I switched to 2G.
See pictures for info
I tried oneplus page "repair phone" so they change my battery but no answer from them (send the request on 19.11.2018.)

I'm in the same boat. Bought mine somewhere in the first months of last year (January maybe?) and based on 35 charging sessions my battery is now on 79% of the original charge (2701 of 3400 mAh). I'm thinking of sending it to repair service and pay to get it replaced because the battery life is noticeably worse even with the NLOS ROM and MicroG.

My 3T will be 2 years old next month. I was facing serious battery issues so after searching a lot, I installed Accubattery and let it analyse my battery usage for a few days. I found out my battery had been degraded to around 77%( no wonder I had to charge my phone ATLEAST 3 to 4 times for a 24-hour endurance, iwas on stock oxygen oreo with franco kernel).
THis july, i got my battery replaced(June END for Rs800 INR) and now i am on OOS NOUGAT(way more BATTERY FRIENDLY and throttles less compared to crappy unoptimised OOS OREO we got).
Battery was fine and lasted more than i needed for PUBG MOBILE. but within a few months, BUT only after 5 months battery quality has degraded to 82% again!!!!
PS:1st image is before getting new battery.
2nd IMAGE: New Battery(June 26 2018)
3rd image: Present (November 23 2018)

I bought my 3T in December 2016, lately I have been noticing a lot of battery drain (everything stock and latest OOS). I have to charge my phone at least 2-3 times a day. However, I have been streaming a lot of video (chromecast) and audio (bt earphones) so I am guessing that could be the culprit. Netflix on chromecast is especially hell for battery life.

Get your battery replaced from original service center

I would take the battery health % with a grain of salt. Batteries hardly every have their advertised full capacity, even straight from the factory. I remember a thread from a while back (older devices - it's been a few years) where an XDA'er tested multiple batteries (factory condition) from various OEM manufacturers, as well as reputable 3rd party batteries. Hardly any met the advertised capacity. Something like 80-95% is about as good as you can expect. Maybe folks on here have some more device specific, and/or more recent data. And obviously, if you took the readings when the phone was new; you'd have a good start point. But the reading now doesn't mean a whole lot. Could have only been 80-90% to begin with. And replacing the battery may be a waste of money and effort.

I bought it april 2017, So That's 20 months now. Usually I charge to full every morning and some at nights depending on my usage. Untill 2 Weeks ago I charged every 6 or 8 hours (while I had the battery drain, happened for about 2 Weeks ) . Last week i moved from open beta to stable and wiped everything. While it's not as critical as before, Phone holds charge Better when screen is off but I still have worse screen on times. Now I don't charge above 90%.

Does this mean that you were charging the phone every time till over 85% and in general you were leaving the device plugged to charger for many hours?
If this happened for long time, then for sure the battery has been degraded.

Question How is your batterylife?

I know it depends how you using it and so on. But generally?
I think mine is worse then pixel 4 xl. Have only charged it like 4 times but still. Using some Instagram, Facebook, Spotify, news , youtube.
Mostly wifi and feels like battery is dropping really fast.

I'm getting 7-8 hours SoT when battery hitting around 25-30% left. Here's my thread from my first findings.
Battery life?
So I'm coming from a 3 XL, and I even got the battery replaced April 2021, and I was getting about four hours SoT. My 7 in only two days is blowing my mind. Yesterday I had five hours SoT, and today after a full charge, It went from 100% to 99%...
forum.xda-developers.com

Today's usage.

its about the same as pixel 6 for me maybe a little less from daily usage...but smoother for sure and the phone is a little bit smaller which is always a plus

My battery sucks ATM. Only had like 3 full charges so might settle and getting better , hopefully

Another quick update. Haven't used the phone that much yesterday or today yet, and I'm happy with standby time. Over 34 hours off the charger with over 4 hours SoT, and still has over 40% battery.

LOL what do you want? 20 hours SoT? Maybe because I'm coming from a 3 XL with a 3430 battery that after 4 hours of SoT, and only being off the charger for 12 hours, not well over 30, my battery would be at 10%, not 40%, but to me this is freaking awesome battery life.

20 would be stellar.

Anyone getting battery drain with Spotify?
Was listening for 3h with bluetooth headphones and it said Spotify needed 23% which i feel is quite a lot.
3h display on used 5%

Mine is honestly making me regret buying the phone. Too late, sent my trade in yesterday.
I previously had the Pixel 5a and got around 9.5 hours of screen on time over 24 hours. I think most days I could go about 30 hours before running empty.
My P7 gets around 6 hours of screen time over about 18 hours.
So a battery that's 7% smaller is seeing battery life more than 30% worse.
I'm not very happy with the battery life as you can tell, and I just hope a software update can improve things.

Other than the battery life the phone is fantastic haha. It's not unmanageable, I do keep good high-watt chargers in most places like home, work, car, etc. But sometimes I go do something all day and I'm not near a charger. Guess I'll just get used to using battery saver mode in those situations.
I do enjoy the phone, but the battery giving me anxiety is not very fun.

Yeah. I guess. Working 10 hrs makes me nervous about battery life. Lol.

dont reference your SOT, reference it to your previous phone, everone usage SOT is different, one person maybe have 5 hours SOT but on the camera for 70% one person may have 10 hours but only use it for texting or internet.

What ways have you guys found to extend battery life during normal use? Without having to severely reduce the functionality of the phone, ie 5g or reducing screen brightness a ton. I feel like a modern phone a lot of the point is the screen and 5g so those I wouldn't want to sacrifice
Are there settings or other apps that can help? I'm fairly new to Android and so far I've been a bit disappointed with the battery life of the P7.

What kind of battery life are you getting? I only play around on mine (Instagram, Pinterest, SnapChat, and some Candy Crush games), and my main drain is Clash Royale, and I get around 7-8 hour SoT with 20% remaining. I switched 5G off, and only use LTE because 5G (at least in my area) is bad.

Man, y'all must've been spoiled with like 10+ hours of SOT with your old phones... I get around 6-8 with 30 hrs total which I think is pretty dang good. But like someone else said SOT will be much different from person to person based on device usage. I watched a 2hr downloaded movie from Netflix with airplane mode on and it only dropped 12%. And with adaptive charging, I just charge it all night which it will charge, slowly, till full until my alarm goes off.

Exactly. My experience is the opposite though. I came from a 3 XL, and by the time I switched from it to the 7 my battery capacity was down to around 2800. My 7 is like a God send for me. 7-8 hours SoT with the same use as my 3 XL, and I still have 30% left, when my 3 XL would be down to 2%. I couldn't be happier.

I came from the OnePlus9 and all around the OnePlus9 is a better device.
Google has a great UI experience, but these Tensor2 chips do not compete in performance or efficiency with the Snapdragon 888s or higher.
Theyre missing a lot of the refinement that Qualcomm has done with the hardware and it shows.
For those coming from a Pixel 3-5 series, yes this is a big upgrade, and many got great trade-in deals which is what made me give this phone a shot. It does not however live up to it's MSRP. Im hoping Google is able to refine things to greatly improve efficiency on these devices.
