Ways to extend battery by changing hardware? - Nexus 4 Q&A, Help & Troubleshooting

Are there any third party companies that make batteries for Nexus 4 with increased capacity? Or are there any cases with a battery attached to it like PowerSkins?

I dont know if you knew, but the Nexus 4 does not have a removable battery. Unless you did and those PowerSkins things charge things wirelessly.

It'd be awesome if the case charged your phone via the microusb charging port and then had its own charging port to make up for it. They've done it for the iPhone, so I don't see why it's not feasible.

Well I know the battery is not removable. But I'm willing to open the back up and switch the battery to a much higher capacity one.

If you want higher capacity you would need a physically bigger battery. It's not possible to make a battery with more capacity and the same size as the original. So this would mean you need a different back and this won't happen since there is a lot of essential hardware on the back plate.
There are currently no extented battery case for our phone. You best bet for power on the go is an external battery pack. I recommend the monoprice 5000mah.

Change the phone to another, all set.

Not entirely true, you can up the battery about 300-400MAH without adding size, just costs more.

i doubt anyone will offer a extended battery cover for this phone. The back of the phone is too complicated.
Even if it were possible to put a higher capacity battery in the stock space...the ~10-20% wouldnt be worth a company developing it for the phone.

manufactures use better batteries than any aftermarket brands including mugen and seidio. They are not going to go to all the effort trying to make the thinnest phone possible and then stick a cheaper thicker battery in there. If you are going by the claims of these aftermarket brands then they are just inflating their capacity. Here's a site with thorough testing of these aftermarket batteries compared with OEM. http://batteryboss.org/

Leaving In Mains

I want to use my Samsung Galaxy Note as a tablet. Sure, it isn't as large as a 10" tab but it offers the same great resolution. However, 5 hours battery life isn't good enough. Someone I know suggested just leaving it in the mains during heavy usage, as I would with my laptop, but would this not kill the battery? How can I get tablet usage out of my device whilst still having battery power left should I have to go out and need a phone?
On the topic of battery, what does power-saving mode actually do?
Lowers MHz, brightness, turns on one core only (my guess)

Thanks.
Will leaving it powered in mains ruin battery then?
^^ I don't think so. When the phone is fully charged, it stops receiving current. So, your phone should be safe.
Also curious.
Thanks. I want to use the device as a tablet but not be left without any battery.

There is a limited amount you can do.
One of the bigger advantages of a larger tablet is the ability to have a huge battery - three or four times the capacity.
Using the note while plugged in is a bit annoying.
One alternative is external chargers/batteries. Swapping batteries every x hours isn't a huge deal.

No !! it will not damage the battery, As said above the phone stops receiving currents when fully charged.
Modern day batteries will out live the actual device, and under extreme pressures it will still live longer than the time you will own the device.
in general not due to technology, however its best not to, wear tear connectors, usb jacket plus risk when accidentslly dropping it bending it etc, etc etc

Shouldn't do. Modern batteries don't suffer with lack of full charge cycles like old NiCd and NiMH batteries used to.
Probably won't hurt to fully discharge it every now and then to help with battery calibration though.
Thanks! Problem solved then.

How do you first charge the Nexus 4 for the best battery life?

I remember as a kid, when getting new hardware, you need to charge it to the maximum and leave it in for a few hours to kinda work the battery and get the most optimal battery life. So for this phone, what would you need to do when you first get it to get the battery to be the best it can be?
Do we cycle it from 0 to 100, or just charge it to 100 and leave it?
Or does it not matter?

It doesn't matter. While older nickel-cadmium batteries could have issues with charge memory, lithium ion batteries are not affected. Just charge and use your phone as normal. If you want to maximize battery life make sure not to place your phone in extreme heat (eg. inside a locked car in summer time) and avoid leaving your phone at 0% charge for any length of time.

For the purposes of this discussion it is identical.
Well technically it's Lithium-ion Polymer
Same thing. Either way they don't have the memory issues that old rechargeable batteries had..

Nope.
These new Lithium batteries aren't subject to any of these myths.
Same with the "Take off your device from the charger once it has been fully 100% charged or the battery will stuff up." Nope. The battery just cuts the charge and just runs down. That's why if you look at your charging history, it might go to 99%, 98 or even 97, and go back up to 100% because that's when the phone decides, "Yep, I'll take a bit more charge."
Alright. Thanks to everyone!
I'm getting mine tomorrow ;D
(Aw, outta thanks to give :'( )
It is good with these batteries to run then down to almost empty every week or so, right?

Another myth. Not true for Lithium batteries
Really? I read this in a battery forum years ago. This was for laptop batteries though..
Not meaning to sound sarcastic, how do you know this? Are you an electronics engineer or something? Just wondering.
Sent from my Nexus 7 using xda app-developers app
Lithium-ion/lithium-polymer batteries don't have the "memory effect" that older nickel-cadmium and nickel-metalhydride batteries did. So there's no point trying to run your battery down low every now and again to help its life. In fact, it seems that charging it more often is the most helpful thing, i.e. lots of small charges rather than big charges all the time.
Just use it normally and charge it when you need, it'll be fine.

How about leaving the phone charging after it is fully charged? Like when you charge it overnight.

The phone and charger electronics will lower the rate of charging as it reaches 100% and turn it off when it's done. You don't need to worry about unplugging it right away.
In longer term storage situations where you aren't using the device (i.e. weeks or months) it's optimal to store the battery at a charge level of 60-70% to reduce battery degradation over time. When the Mars rover \Curiosity was en route to mars the batteries were at 60% and were charged upon approaching the planet.

I am an electrical engineer actually. Li-Ion or Li-Po batteries do not need to be treated any special way. The only thing that degrades them is use and time. And it does not matter how deeply you discharge them (discharging to 50% twice is about the same wear on the battery as discharging to 0% once, within a reasonable degree of error).
What you may have been reading was with regards to calibrating your laptop's battery meter. There is some truth to that, and allowing even your phone to discharge completely (down to 5% or so) once can help make sure your battery percentage is accurate. But it does not affect your battery life at all.

Actually, it doesn't say to do it "first". It says "its a good idea to fully charge *as soon as you get a chance*."
The wording in the quick start guide you provided doesn't seem to imply that its a critical thing. It seems to me that they are putting that there in case someone takes it out the box, starts playing with/using it, then wonders why the phone is already dead. Then they post to XDA about how the battery life sucks. (Just kidding! )

Charge using different charger

Hey i just want to know it is safe to charge this phone using 5 V 0.7 A?
Because i see in the normal charger, the output rating is 5 V 1,2A.
I am currently using my previous samsung charger (5 V 0.7 A) to charge my nexus 4. It is safe or not to do this?
I dont mind for if the charger take more time to get my battery full anyway.
Thank you very much

No problem. You'll start running into problems when you use a charger with higher Amps than what you phone charger puts out ie a tablet charger. Good luck!

A piece of electronic equipment only uses what it needs as far as electrical current is concerned. I am using a 2.5 Amp cigarette lighter charger with my Nexus 4. I could have used a 5V 100 Amp charger if I wanted, although it would have been tough trying to fit that giant connector into the micro usb port.
^ +1 You should have no problem using any charger that adheres to the USB spec and provides 5V reliably.

Nope, it would just insta charge your battery pretty much.. It probably would damn/fry itl; but only because the battery got hot.

Even that is unlikely because the phone regulates how many amps to draw. The current allowed is regulated based on multiple factors including the battery temperature and the charge present in the battery.

Well the second scenario was if said bits failed
amps / volts
Think of volts as pressure, and amps as volume of flow.
Think of a conductor as the empty space of a pipe, the insulation as the pipe wall.
Higher volts needs stronger pipe (conductor insulation). The limited insulation in most modern electronics will burst if to much pressure (volts) is applied, causing a short and a fried device.
Higher amps requires a larger pipe (conductor) and will most always be limited by the size of the pipe, or the amount of volume consumed downstream.
If a charger puts out 100 amps and only .75 can fit through the pipe under a giving pressure (5 volts), then only .75 amps will be able to come out of the charger, without damaging anything.

Revive Palm M505 with Nokia battery?

Hi,
I just found my palm m505 from my storage room. The battery is about to explode so I removed it but I can't find cheap price for battery replacement. So I wonder, is it possible to used nokia battery which is Li-ion 3.7v. Palm m505 use Li-polymer 3.7v.
http://img.ihere.org/uploads/e76f9fa965.jpg
I did cut the wire but I'm not dare enought to stick the cable to the nokia battery directly. Is it possible to use Li-ion on Li-Polymer devices?
Thank you for any recommend.
Best Wish,
Jeng
Its ok now... I just try it myself. -.-' Thanks anyway.
Just saw this thread now, surely it worked for you. Everytime when you will use battery with the same voltage will work, doesn't ,atter if it's li-jon or li-pol

There can be big differences using batteries not designed to be charged by the host's charging supply, the battery chemistry is vastly different, as will the rate of charge/discharge when moving from Lithium polymer, to Lithium Ion.
Both of these batteries require different charge adaptors and charge rates/currents.

Have you considered using a battery pack as needed? The first advantage is that your phone continues to fit in your pocket and doesn't look like a 1980's mobile
You only need to connect the battery pack to the phone for an hour or 2 till it picks up sufficient charge for whatever you're doing.
When not in use the battery pack can be kept in a bag, pocket etc out of the way.
The capacity of a battery pack is lineally proportional to its volume (well, the cheaper ones provide less capacity compared to a good brand), and you can get anything from 2000mAh (almost the capacity of the Nexus battery), up to 11,000mAh+. Not sure why you'd need 11,000mAh unless you were going to the jungle for a week, but it may suit some people.
I have had a 5,500mAh pack from NewTrent for a couple of years now and it's a good compromise between capacity and size. Check them out on Amazon, they often have heavily discounted offers.
Some even include the cable connection integrated into their body now, so they are very convenient. I would not consider a battery case, since the battery pack option is cheap and very convenient
