That's what I said... man its like carrying a brick in your pocket!!!!!

Hahaha. Now they need to make a backpack carrying case for the phone + extended battery.

hahah yeah this would be one hell of a thing to put in your pocket.

3000mah docking station/cradle?
Anyone know if fuze/touch pro, with the 3000mah battery, will fit into 1350-1500 mah docking stations/cradles? If not, anyone know where to find a cradle for this beast.

Nice try! Plus a huge antenna on top that sure will bring back some good old memory...

Maybe a nice little leather bag like the 3-watt bag cell phones I started out with! :-D

LoL
anyway,
what is the reasonable price for OEM battery (that 1350mAh).
I am looking for replacement battery since tp drains battery fastly if I use it for GPS.
I have two choices here:
a. Replacement/OEM battery
b. Pocket charger (basically it saves electricity, 1600mAh or so) it cost around USD 16
I live in Asia btw, and TP battery is a rare item. Once I found a htC P4700 battery, it is for sale for around USD 34.5

For that size it should come with a heat sink and fan!

What I want to know is how good the camera and flash work with that extra size. I hope it doesn't interfere too much...

DIY Battery pack for Iconia Tablets

Most of the guys here at XDA are familiar with the hardware components inside Iconia tablets as well as very fond of all hardware weaknesses and strengths of that particular device.
As no surprise its battery capacity is …I would say, insufficient for that kind of a portable device especially given what brilliant job the engineers from apple had been done to Ipads.
Anyway, let’s move on the subject of this post.
The original battery has the specs as follows: 7.4V ,3260mAh .
My experience was quite straight forward – 3.5 hours video playback (display 60% dimmed down) ,4.5 hours wifi browsing/downloading , after 8 hours in stand by ( Wifi ,GPS turned off) battery drained about 25 percent .
That’s very close to a regular notebook and is not exactly what I expected from a 3G / Wifi tablet.
The good news is that not only Acer’s devices are paired with short lasting batteries, so no one should regret choosing Iconia tab, and even better news is about to come soon if we can craft our own supporting battery and make this gadget work overnight .
The battery charger is providing current of 12V 1.5A (1500mAh) and 12V is happen to be one of the most popular voltage used in cars and therefore wide range of cars accessories as well as security cameras and so forth. A brief eBay search led me to a Chinese made super duper battery for security cameras which may be my happy ticket. 12V 9800mAh sounds like a spoon of honey to me. Of course the battery pack looks horrible (OEM cells, blue PVC insulating tape) but it cost less than you might think.
If paired with fancy spiral cable and appropriate DC jack this 350g battery may fit comfortably in your leather belt pouch and feed your lovely monster tab for about 6 + hours
The real power consumption of the tab is about 3260mah / ~3.5h = 800-1000 mA
After simple math we may see that battery with 9800mAh may charge the tab for about 6.5 hours
So my way of thinking is with fully charged internal and external batteries we have about 3.5 hours internal capacity then charge for about 1.5 hours (totally 5 hours ) then another 3.5 hours on internal battery then charge 1.5 hours and so forth until the supporting battery pack is almost drained. If the math in the following chart is correct we may recharge the internal battery up to 4 times without being chained to the wall socket

So my hope posting this thread is that someone might like to join me in this experiment and share the results. I’m not an electrician and perhaps I may be wrong about my expecting results but if so, I’d like to be advised by someone who knows more than me and would like to put his/her contribution to get this mission complete

Uh. You didn't post a single question, what do you expect? Someone to confirm that yes, the external battery can be used to charge the tablet once you make a proper cable for it?
Yes, it can be used for that. And yes, it'll provide several hours of extra mileage.

It's the general section, no question required. Its a discussion, get over yourself.
Edit, I see it weighs 300 grams, pretty light. Do you have a link?

I think it's a pretty sound idea. My question would be, how do you charge the external battery pack?
Most devices have an internal voltage regulator, that shuts the connection when a battery is sufficiently charged to prevent over-charging. Without this little device, you could overcharge your extra battery and possibly explode it.
Charging units (comes with the tab) only convert from AC to DC, not regulate the cut-off supply, at least as far as I know. So you would have to devise a method to supply the correct amperage and voltage, and, shut off when charged.

I got one of these external battery packs. I keep it in my backpack, and it'll recharge my tablet and phone several times over.

Question, what do you use to re-charge the external battery pack?
Inquiring minds wanna know.....
EDIT, just checked the link. Too bad there's no NewEgg in Moscow, but lots of chinese batteries!!!

It comes with a charger, you plug it into the wall, or your solar panel, or your car.

Thanks! I will save that and order one soon, as I am looking to do a prolonged photo shoot with my tablet in "follow-mode" displaying the shots as I take them, and was looking for a reliable way to keep it juiced.

Modify stock battery of a phone for extra mAh by add one or more batteries

Hi all hardware mod experts/hobbyists.
As we are all moderate to heavy phone users, we need a phone with a good battery life that won't die before evening. However, everyone seems stick to a hone that could work with screen on less than 6hrs, even 3000mah won't help much.
Now, I want to add 1 or 2 more batteries connect in parallel to my current stock batteries. I hope it would multiply the juice, however I would concern about Charging Voltage, safety charging current from Charging IC inside the phone, and Charging Duration. Of cause, adding extra battery will make your phone Fat, ugly and heavy but we have better battery life.
battery type : norminal voltage of Li-ion 3.6v or 3.7v, Li-Po 3.8v and some other battery even mention 3.9v or 4.0v .
Full charge :4.2v.
Charge voltage 4.2v
Current : depend on the phone
duration = capacity / current
Please upload your modified phone by add extra batteries, with your usage experience.

i found this for iPod Touch 6th Gen. He modified by soldered another battery on the back for tripple battery life

I think it is better to use a power bank, safe, easy,maybe not convenient

Yep.... It is better to use power bank.... To embed 2 or more batteries may give better time but looks too odd...
???

I'd recommend to if you're gonna add another battery do it with another of the same type because phone Power Manangment IC could have troubles trying to read two or three, if wanted, different batteries, in some cases they have different data read pins(the ones that are not positive and negatives)
Sent from my XT1058 using XDA Free mobile app

If connecting batteries, they should be same voltage and amperage. To get longer run times at the same voltage you connect both positive together, and both negatives together. If they are the same, lets say 3000 mah, then you while get 6000mah. Approximately twice the run time. If one battery is 1500mah, and the other is 3000mah, then you will only get 3000mah when they are connected. They will both only charge to 1500mah, or the lower amperage. If you connect the batteries from one positive to the other negative, on a 3.2 volt battery, then you will double the voltage to 6.4volts and blow out circuits on your device. Personally, I carry solar charged battery packs. I also have an AGM battery for a lawnmower that is 300amps, which will charge my phone for weeks. Any questions feel free to ask. I was a yacht mechanic, so I had to install and fix DC and AC portable power systems.

You better try some software optimization to get a better battery life,like a custom ROM & kernel, root your device,a good app for battery & performance boost which personaly use is called greenfy and it realy improves the battery life by hibernating apps,anyway 3000 mAh should be enough for most phones and better you lose your warranty rooting it,not trying to burn your phone's circuits with other batteries

Hi ! got 5000mah battery installed on my OP3, but it still says OP_3000mah.. How to modify this? Does this need to be rooted? Thanks!

Hi,
I recently did this to a Samsung Galaxy A3 2016 that I had multiple units of. One had a good screen and a battery, but the board was dead. The other one had a dead LCD and no battery. I turned them into one.
All you need to do is make sure that the voltage of the batteries is about the same, and then just solder the + of the first one to the + of the second one and the - of the first one to the - of the second one. Make sure to solder it to the pins beyond the battery controller, so that the second battery doesn't overheat or expand. Then just insert/solder the whole thing into the phone. DON'T use cells without a charge controller.

This is what I did with the housing afterwards. I screwed 2 separate frames together, which allowed me to house the second battery with no problem. No glue was used and this is very solid.
The pictures are old, I later put a camera lens on it and a new back. I also got a separate NFC antenna, which I stuck on the top battery since the original antenna is on the bottom one.
I hope this helps.

And as for the battery capacity being displayed in the phone, I'm sure most applications such as AccuBattery or Ampere just display the capacity according to the model of the phone. I know that phones CAN measure the voltage of the battery (or batteries in our case), but I'm not entirely sure about phones being able to measure the capacity of the battery on their own. I know my modded phone displays 2300mAh despite the actual capacity being around 4400mAh after the mod.

My Nexus 6p charging slowly according to the ampere app,its showing less current.help

Please help
Want to knw is it the app defect or my phn defect?
With my stock nexus 6p charger it showed me max current of 1500mah whats wrng?
The day i bought the device it showed me 2950mah.

A couple questions regarding your issue:
Is this the charger that came with the phone, USB Type-C on both ends?
What was your battery percentage when this measurement was taken?
What were you doing on the phone at the time of the measurement?
I assume from your post that question one is a yes. I ask question two because as your battery gets close to full (and in the case of most lithium battery charging) the amperage will lower to finish topping it off. Question three is important because I believe the Ampere app shows the net total amperage flow. Meaning that (a mA in) - (b mA being used) = (c mA total flow). So if you have brightness to max, music playing, etc. then the total mA flow will be lower.

Yeah am using the same charger usb c to usb
And i checked it on all percentages it ws same it never exceeded 1500 and sometimes it showed me 600 also
I was not doing anything at that time
Just charging my phone what should i do now?

Hmm... I've gotten weird readings from Ampere sometimes. Give the Current Monitor app a try perhaps.

same issue and haven't found any solutions so far

Could be the charger being defective, hard to say. Or the USB C port. Check if there is lint build up in the port.

It's ****ing weird. Never had these sort of issues using the QuickCharge 2.0/3.0 and micro-B connectors.
I cleaned out the port with isopropyl alcohol and compressed air. I've got some 3rd party chargers that register as "charging rapidly" but have yet to see current even close to 3A. Using the same cables, the OEM charger is still stuck on just "charging".
I can't seem to really push past 1.3A regardless of battery state, charger used, or cable.

By comparison, this is what it looks like with 3A charging. The bulk charge rate is near 80% per hour.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Samsung Galaxy A7 (2018) can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

From 8% to 100% mine takes an hour more or less

Now this is interesting.
I am using usb power meter alongside the supplied charger and cable in the box and I found that even after the phone showed 100% charge it continued to draw current (~300mAh) for another 20 minutes until stopped entirely.
So my total charge time from 0-100% was 2 hours and 44 minutes.
Also for the first ~60% charge the phone draw the full 1.55 amperes and after that gradually dropped down to 0.50 amperes.
While the charger runs little bit hot the phone was cold the entire time.

2 hours to charge from 15% to 42 %
too long

This is way too much. You have probably got defective charger/cable.
But! If you are trying to charge it from a pc then is normal as regular usb ports supply only 0.5A instead of the 1.55A from the original charger.

I just realize charger is defective
Should i fix it or buy new one
Idk if its the cable or adapter

Nowadays chargers are basic inverters with few more stuff.
They have very few components inside but sometimes, usually after hard hitting/dropping on hard surfaces the soldering can get damaged with varying consequence between simply stopping working to working abnormally as lowering voltage, current, overloading and many other things.
For example I had a strange case with fully working charger with healthy components and solder joints but was working on random intervals. It was caused by solder whiskers touching nearby naked track and causing shorts. If it was cheaper charger it would blow, but in this one the overvolt protection was able to save it.
And this is why you can just buy usb power tester like this one

or even simpler like this one
so that you can check what kind of power your phone actually receive from charger/power bank/pc etc.
Our phone does not have fast charge. As such it will not charge faster no matter how powerful charger and cable you can equip it with. For example I have one with 2x2.4 Amperes supporting QC charger mods and etc. - it will draw only up to 1.55 Amperes within 5 Volts range.
The normal USB 2.0 port can supply with max 0.5 Amperes, USB 3.0 within the basic implementation can supply under 1 Ampere.
In simple language this means with usb 2 it would take up to 8 hours to charge from 0 to 100%, with usb 3 it would take about 4 hours and half from 0 to 100% battery.
Of course depending on the manufacturers you can find usb 3 and 3.1 ports that are able to supply way more current, even values like 3 Amperes and higher.
This is why the best way to charge your phone is to use the supplied charger. The cable is also very important because of the current depending on the used wire gauge.
With cheap cable (using thin wires) you would not only be unable to use the available current, you can find yourself in the middle of fire.
But there is a big problem, the price sometimes doesn`t represent the needed quality.
Notice I`m not talking about durability. I can show you cables strong enough to endure 10 kilograms but with so thin wires that can`t carry over 0,5A trough them.
Put your trust only on products that are widely commented and tested by the buyers.
Now, I have tested the cable supplied with the phone. Although it easily handles the 1.55A current used by the phone if you put over 2A it will get really, really warm. This means the wires are big enough but are not expected to handle high current. In simple words don`t use this cable for other things than charging this phone, just to be safe.
=====================================
TLDR;
If you don`t have the necessary skills don`t try to repair it. Any repair error can easily make it burst in flames. Better try with another charger but make sure it can get you at least 1.5A otherwise it would take really long time to charge.

Is there a fast charger available for this phone??

yes, I recommend oppo charger. In just 2hrs the batt will be full.

Is there a way to charge faster? In my case I can charge my phone maximally at 5.19V / 1.42A. Charging from 0% to 100% phone with such parameters takes more than 3 hours, because amperage is adaptive.
