Request to Mugen Power to supply us better battey - Nexus 4 General

hello to all nexus 4 members. due the low life battery of the nexus 4 i consider to requesst from Mugen power to create us
better alternative to make a battery like 3600mah or more. for you who didnt know mugen power are company that makes extened and very strong battaries alternatives to a lot of smartphones. here the website
http://www.mugen-power-batteries.com/
you can google reviiews and youtube for comprasion for stock battaries and their battaries. i found that there are cases that their battaries are twice stronger than normal battaries. ok back to our issue- i know that the battery of nexus 4 is not
replaceable but i read this
http://forum.xda-developers.com/showthread.php?t=2013947. so now with little work anyone can take out his nexus 4 battery.
the problem is there is not alternative in the market i thought that if we (a lot of members of nexus 4 of this great forum)
will ask them in 4 ways

to mugen power they will create some good decent battarey for us although its little complicated to take out the stock battarey.
suggestions? opinions? can it work? i say lets blast them with requests. if they will see thare are a lot of future costumers for thier product they can make us some unique battarey.

They are a company based out of Hong Kong. They will definitely jump in IF there is a demand for it.
In HK, Samsung is the king in smart phones so it might take them a while to build something that is too new.
With the shortage now, I think it won't happen soon.

MUGEN cheats the mAh rating though

The nexus 4 doesn't have poor battery life. Mine gets awesome battery life now that I do not have a bunch of widgets like hd widgets going.

The nexus 4's somewhat bad battery life is solely software related. Just wait for someone to figure out where the wakelocks come from and you'll see great battery life.
Also, undervolt your CPU and you should be getting close to 5 hours screen on time.

3.5 hrs screen time and within that 1.5hrs game
I do not consider this bad battery... Especially when this gab m me I'd a battery hog and requires a lot of resources to run
Sent from my Nexus 4 using xda premium

the battery is good, its software releated, if you want more life you could use setcpu and restrict your speed, I got mine max at 800mhz and its fine, 4-5 hours screen time is possible with this phone,my best is 5 hours,22 hours on at 1000mhz max

Same here, I'm getting pretty amazing battery life. I get about 5 hours screen on time with just about a days worth of battery. Or I get about 2 days of battery on lighter use (about 3-3.5 hours screen on). For me wifi is on full-time and brightness is lowest at night and just less than 50% in the day.
I'm on Franco's kernel with no further changes.
Sent from my Nexus 4 using xda app-developers app

I'm at 5h of screen use right now (PA stock kernel) and I think it's quite good actually. I wouldn't have said no to a Mugen battery pack but since the N4 have a closed back it's not just a matter of simply posing a new battery cover, it would be to much hassle for me. I would purchase an external USB battery pack instead.

Was getting poor battery life, Google Services Framework was the top culprit.
I disabled maps location updating and now battery life is fantastic.

Amazing battery life here as well. Running LTE and max brightness. Take that! In my opinion, as long as it lasts a day then I am fine. I hear people who claim that they get 1.5 days on their iPhones. Instead of charging it at night they keep it till the next day then scramble around panicking when they need to find a charger at mid-day.

First, I'd like to say that I average 4-5h of screen on time with my N4, and my battery easily lasts throughout the day, even with my heavy usage. Here's a screenshot of today, for example:
But if you really need an extended battery, rather than Mugen, I'd actually like to see Anker do one for the N4. I have a 1900mAh Anker in my old HTC Sensation, and it's a world of difference compared to the stock 1520mAh battery. It's also the exact same size, so no special cover is needed. It's slightly heavier too, so all things considered, I'd bet Anker isn't lying about their mAh rating. They get solid reviews everywhere, too, which is why I chose them to cure the awful Sensation battery issue (if you think the N4's stock battery is bad, you seriously need to try that phone! )

No battery issue here..

Bigger batteries.. is it really worth it?

I've really wanted to get a bigger battery, not necessarily a bigger phone. I was looking up videos on youtube, and I found a guy who actually bought one of those verizon silicon cases and used that instead of having a new backing for his phone because the battery was so much bigger. Do you guys really find not having to charge your phone for 20-30 hours worth the extra cover and stuff? I'm sure it's not an option for everyone, but why bother with that if you can just charge it sometime in between? Car chargers are cheap, and there should be some time of sleep between 20-30 hours of you using your phone (you know, where you could be charging it). Also, what is the biggest battery you can get without requiring an extra case?
The 2150 mah battery is perfect for me. The new back protects the camera lense and the leds. I have also noticed that I can hold the phone by the extended back and it feels more comfortable then before.It doesn't add that much weight and the phone is still pretty slim. Obviously I also get improved battery life as well.
I have been using the 1750 battery and it improved my battery life from 6-8 hours to 9-12ish, which is perfect for me. I just needed to make it through the work day and the regular size works for me.
I couldn't go to a bigger battery, since I have a case that works for me and I don't want to change.
Sent from my ADR6300 using XDA App
My 2 cents... I have the 2150. I still go through it once or sometimes twice a day. I dont like the way it feels in my front pocket and the fact there isn't much at all if any accessories that will fit it. I just ordered (4) 1500mah batteries and 2 charges off of eBay for a whopping $20. shipped. I can use the 2150 when I am out and not near a charger or just sell it and carry extra 1500's if needed.

At that price, it sounds like you bought some off-brand garbage. While I hope that's not the case, could you please confirm/deny? What brand are these batteries?
I need the extra battery...was out today using the stock one and was dead after 5 hours (3 hours I was using My Tracks on my run). I don't care about accessories, I just need it to not run out of charge.
I find the extra ummph in the 2150 battery to be worth the lil bulge in the back....modded a silicon case with a cutout to let the excess...works pretty well and couldnt be happier...the only downfall i found so far is the charge time is nearly 4 hrs from a completely dead battery...never really timed it but it takes a while, but worth it.

I'm not sure which one he's using, but I'm using the Seido 1750. My battery life is...decent, I guess. If I bump charge. After reading so many threads on battery life for Android phones and, specifically, HTC Android phones, I'm left wondering a few things:
1. Since HTC seems to have issues charging batteries fully...if we're wiping Battery Stats appropriately (assuming you are rooted), does the phone actually "register" that it's got such a large battery to charge? Or is the phone so stupid that it stops charging it at a 1500's capacity?
2. When apps sync their data, is Android OS smart enough to have them sync at the same time? Or, does my 30 minute Facebook sync occur 10 minutes after my 30 minute Twitter sync, etc.?
New to the forums guys, it was a round-about way I got my Incredible, extended battery, and seidio battery but here is my opinion on this. If you're not gonna use it heavily throughout the day then you can get away with the 1500/1750 batteries. But if you think you're gonna get some solid use out of the phone for a day, you don't want to have to charge it throughout the day, or you don't want to have to rush home and charge it before you go out then you should get an extended battery. Using both over the past week to see which one I want to stick with, the extended is just more convienient since I don't have to think about how much battery i'm at and remember to put it on a charger.
There is a guy on here who modified his case to accommodate the 2150 battery and after seeing that I think that's what i'm gonna do. If you can get the extended cheap then definitely go for it, its just more freedom in my opinion.
Why do you want to go to an Incredible? I thought the X was a better device. Just too big? I have yet to see an Evo or X so I have know idea how big these things are.

did you get lost? your in the Incredible section of the forum, so there will bee a predominant amount of Dinc users here.
And I'd rather have an Incredible over that piece of Moto anyday
I recently bought a 2700mAh extended battery. I don't mind the extra thickness, it allows me to get a better grip on it. As for battery life its great. With the stock battery I could barely make it through 8hours at work. With the new battery I have made it 10hours and counting. I have had GPS, Sync, WiFi, and max screen brightness on all day and only at 73%. Made a few phone calls, and a few Twitter updates. Was worth it.
Sent from my ADR6300 using XDA App
No I didn't get lost. I was just curious what he did not like about the X. I would rather have an X but HTC phones are much easier to hack. A Dinc hacked on to Sprint Sero is hard to say no too. I would have done an Evo but used prices on an EVO are still ridiculous and I'm waiting for HTC sort out it's display issues.
Back to the topic at hand. I'm liking my Seidio 1750. With some tweaks I'm getting better battery life then my 3GS got. I make it through a whole day of moderate usage (some web, some streaming and 5-10 calls) and still have 20% at bed time. So I'm quite happy. Someone did point out a thread on Android Central. I won't return the battery but it did dampen my spirits a little.

I have had the 3500, for a week. Lasts 2x the 1750 (have one) and the door design is more rugged and protects the lens well.
Worthy purchase.
I had the HTC 2150mah and returned it. I just couldn't live with the bulk.
I bought both 1750 and 2150 from HTC Pedia. They are both HTC BRAND batteries. They both work well and add work time to my INCREDIBLE. Don't buy anything but brand and you will be happy! I found HTC PEDIA to be the best place to buy accessories for my phone!

My battery lasts 8-12 hours depending on how bad I beat on it.
My active days, I listen to music, play suduko, check xda, play in the market. Listen to tune in radio.
That said. I don't know if that is short. I think it's pretty long, and am happy with it. I have the decrapified rom, love it. I have App Killer by Rechild set on a widget. So I go in set what I want it to regularly kill, and tap the widget through out the day. It's mostly my android process that hogs the battery according to widgetsoid.

I was averaging 9-12 hours with decrapified 1.1 depending on use. JuiceDefender extended that another 1-2 hours but added 4-6 seconds before I get 4G back when the device "wakes up". It turns the radio off and I have it set to ping instead of constantly syncing. 3G comes on 1st, then 4G...

Sounds ridiculous but i turn airplane mode on when i'm not using the phone. Turn it off every couple hrs to see if i got any emails or texts or something. Huge battery savings. I have the accurate battery mod posted in the dev forum so if i wake it up after sitting for an hr it's down 5% if i leave airplane mode off, but if i turn it on, it's down like 1%... maybe.
Once cm7 is available, we will see huge battery improvements, i have no doubt. Gingerbread is much better w/ the battery than Froyo. I saw huge improvements between cm6 and cm7 nightlies on my droid, to the tune of 200% standby improvements. Still heavy use i wouldn't expect more than 15 hrs, but imo 10 hrs is ridiculous. There's not really a huge difference between heavy and light use in battery time either.

good to know! thanks. when is cm7 available for the revo?
Thecubed is currently working on it.
Buy an extra battery and wall charger off eBay... Throw the battery in your back pocket, and you're set all day. I swap the battery out after about 8 hours (when I get to about 20% battery) and I'm good the rest of the day. I've had to do this with EVERY Android phone I've purchased. The OG Droid would only get me about 10 hours right when I got it, but Undervoltage Kernels, and decent Rom's brought it up to around 16 hours on the standard battery. The Samsung Fascinate was horrible - Roughly 6-7 hours out of the box. Rom's got it up to around 12. The Droid Pro - 8 hours at most on the standard battery, never saw any improvements with my usage. Droid 2 - 10 hours out of the box, but when CM7 came out on it, I was averaging around 16 hours before I got the Revo. The 8 hour battery life didn't surprise me. I kinda expected it, and had already placed my battery/charger order before I went and got the phone. I'm not a fan of extended batteries just because of the extra bulk, plus finding a case w/an extended battery is a PITA. And the 3 minute downtime from a battery swap really isn't that bad (especially if you've ever had a Blackberry).

Agreed, I don't buy from overseas with the battery but the charger really doesn't matter. I got a genuine LG battery for $19 and then just a generic charger for it for $8. Knock on wood I haven't had any problems with the chargers I've gotten, but I don't trust generic batteries either.

4326mAh battery, 2A charger, 2.1 hours theoretically. Realistically, 2.5-3.0 if pretty much empty.
If you're using a non standard cable or charger, who knows what the charger is actually outputting. If you're charging from your computer USB Port, that's 500mAh, so 8.6+ hours. Some random phone charger, probably 1000mAh, 4.3+ hours, etc.
The brightness of the display adds to some of the drain I notice, when possible I keep mine somewhat on the dimside, obviously if I'm in an area of bright light and it hard to see then I'll crank up the brightness.
Can't complain about battery usage.. It's amazingly energy efficient even on a stock kernel considering the horsepower this thing has.. I average 20hrs or so with moderate to heavy usage.

I've had really bad drains since 4.1.2. I think I've narrowed it down to an issue with Google Play. I've noticed it several times - Very good battery life, but then it will go down fast, even when sitting unused. If I check battery usage, Google Play is always number one with >50% of the use.
If I force close GP, all will be well for about a day, but eventually it happens again.
I also felt it, but only by that much...not too obvious. From full charge, after only night idle, drop 3 percent compare to last time 1 or 2 percent

Same problem, battery drain is faster, with normal use 12 hours (before 17) and when charging phone it's just 99%. With factory reset same resoult. Now I try without all gps conections.
Anyone have good solution?

How often do you charge your nexus per day?

Like the title said. How often do you charge your Nexus 4 each day. Pleas take into consideration that you let your N4 run at least under 30% before charging. If you can go on without recharging your battery for more than one day please post the numbers of days.
I charge once a day. I get 12-16 hours of battery life from what I consider an average day attached are screenshots from yesterdays battery life

Yep, same. I've even had 40 hours out of it once, but only because I was in meetings for 2 days and the screen was off for 8 hours at a time. that was fully charged to completely dead.

Depends. When I'm at home I charge once per day, but when in at work it just sits on my desk charging. I normally use the phone more at work then I do at home, so it's hard for me to tell if I could really get through a whole day work my normal usage. I have done about 12-14 hours or so with a couple hours of screen time and still had 15% left. To me, the battery has been about 25 percent better than the gnex.

Yeah, I am having intermittent camera issues, a lot of photos come out black even in good light.
It's another excuse to upgrade I guess, has been a great phone though.
I think I should try the battery swap thing, mine just cannot get more than an hour and a half of SOT no matter what combination of ROM, Kernel and Android version I try, and using it during my daily commute means I arrive at my workplace at already 60% even if I'm on extremely low screen brightness. Greenify doesn't help either because it's the actual screen on what kills it, as long as the screen is off the battery drain is negligible.
Worst part is that every single battery out there is a fake, just with a very high-quality copied sticker on it. AFAIK the only way to get a new original battery is through LG and for a price you'd be better just getting a new Moto E 3rd gen for a little bit more and call it a day.

The old battery would no longer charge at all.

I have decided to give it a go, what sort of screen time is your replacement battery giving you, was the battery from an Amazon Marketplace seller?
almost all day pluged on computer lol

You do realize its capacity is anywhere from 2500 mAh to 3100 mAh, not really 4000 mAh? It's physically impossible to fit bigger higher capacity cells into single OEM battery size. Typically these ebay batteries, like Golden 4200 mAh, are closer to 2500 mAh (I have tested a few), but from your screenshots and the fact it costs over $10 - I think its safe to assume it will be closer to OEM 3100 mAh. Just gotta watch out for any bulging which happens with these over time especially when you charge them at full 2A speed, and you probably going to notice performance to go down in about 3-4 months.
Sorry bro, didn't mean to rain on your parade. It's just a fact with these ebay batteries.

Well it doesn' t seem much, if any, better than stock battery.
It is surely better than my stock battery. So it can't be less than 3100mah. Has to be higher.
It is not physically impossible. Not sure where you got that info from.
You didn't rain on my parade. I have results to prove it. My stock battery is now used as back. No use for it day to day now.
Only idiots buy golden battery lol.

Ooh, you just offended a bunch of people on this forum who got Golden batteries hoping they will get 4200 mAh for $6
Unless you have some latest ground breaking info about new development in battery cell density, Samsung used the highest density battery in their OEM footprint. It's a fact. The only way to maximize it was by doubling the size, thus all the reputable companies had double thickness/capacity with 6200 mAh batteries and Zerolemon had it at triple with 9300 mAh. The only company that was able to squeezed a bit more was Mugen who does their own development and was able to squeeze in 6400 mAh in double capacity.
To verify capacity of your battery, looking at performance with screen on time, etc is not accurate. Especially since you are comparing it to an original battery with aged performance. You need to get an external hardware battery tester where you charge the battery to a full capacity and let it discharge down to 2.4V cutoff voltage while monitoring the actual current drain over time to get the exact capacity in mAh.
Btw, just for sh!ts'n'giggles, take the label off your battery to see what is stamped in there as actual capacity
I dont need to get anything. ..
My real world usage proves this last longer than my stock battery. I bought this battery to use as a backup but now my stock battery is the backup.
Are you saying mu screenshots are fake?
Also if you're point was valid, aa batteries come in one size right?
Why are there 800mah, 1200mah and 1600mah aa batteries?
I am happy and surprised with my purchase. Doesn't matter what you might think. My screen shots prove it.

Chill bro, I'm not doubting your screenshots or your experience. As I said, it sounds like you probably got 3100 mAh battery. That's all. As someone who reviews a lot of accessories and gadgets on XDA (http://forum.xda-developers.com/showthread.php?t=2192333) and helps other members on this forum, I just want to be sure other people are not mislead by thinking they can get 4000 mAh battery because Note 2 battery with such capacity doesn't exist. Period. Neither does anything over 3200 mAh since I remember testing my Anker 3100 mAh to be slightly higher then stock capacity. The screenshots are real, I'm not doubting it, but that is call a "relative test" to another reference of someone else using stock capacity battery under different conditions with different setting and running different apps. We had people reporting poor performance with ZL 9300 mAh while the fact is they were comparing it to stock battery performance from 3-4 months ago when they had different setup with different apps, etc.
Just calm down, enjoy your battery, and spend a little bit of time reading this website with a lot of Note 2 battery reviews and explanation how they really being tested: http://www.batteryreview.info/
Ok just making sure you aren't hating lol.
I didnt say I believe it to be 4000mah. I just believe it is higher than 3100mah because it lasts longer.

We only got love on this forum
It lasts longer cause its a new 3100 that hasn't degraded like the one you are currently used to.

My stock battery has never lasted like this under my usage.

It's probly a case of new 3100MAH compared to your used original 3100MAH
Only new battery tech could squeeze juice more into the same physical battery.
New battery tech wouldn't be sold for $14. :good:
Anyway at $14 that's not bad. Let us know how it performs over time. Cheaper than buying an original Samsung 3100mah
Just got this
Just got this battery and managed to last over 7hrs of onscreen time doing mostly messaging, web browsing, watching videos off the microsd card and youtube.
Auto-brightness was set to about 30% (was more than sufficient for an overcast day and 8 hours in the office).
Had location services turned on, gmail and Exchange syncing. Also had music playing (Poweramp) for most of the work day.
Hope this helps any others looking to give this a try.
No idea if I will get this sort of screen time on the stock battery as I've only had a half day use of it (bought the phone used off ebay and got the extended battery at the same time).
I get these same stats on my stock battery. Running ADHD 18 with latest Perseus kernel

Im not impressed
As i can see your screen on time is just 4+ hours, i can say im getting somewhat 6-7 hours screen on time with my 7 months old stock sammy battery
As far as I'm aware the Mugen battery is the best available at 3200mah. The Anker one being a better value for money choic3 at slightly higher than stock.
I have no way of actually testing this though, but there's no way the OP's battery is anywhere near 4000mah.
On a similar note, does anyone know of any tools to accurately measure these battery capacities?
–edit sorry wrong link that was for testing cords not batteries
gNOTE2 rolling in the north
I see the reviews here are pretty old now.... so can anyone of you update the status of your battery performance now?
im sorry but i think zerolemon is better with 9300 if u dont mind the bulk
