Build a new battery

---

Hello,

i have an idea because the battery of my DELL Streak 7 is quite bad. So i thought, if i get another li-ion battery from a notebook for example, i could build it into the device. Would it be detected?


greetz.

I think it should, I mean why not, provided you do the connections properly. 1 thing, the battery specs perhaps must be same or nearly same as the original battery.

What do you mean with specs? I need a more powerful battery so the mAh should be different.

Main problem is:
1) If the Streak uses an in-pack fuel gauge it could be difficult.
2) Getting a battery of the correct dimensions to fit is going to be extremely difficult

However, if you don't mind issues with form factor, you could:
Make a dummy battery from plastic or wood
Run wires out from this dummy battery to an 18650 holder
Put in a protected 18650 - easy, 2-3 AH battery.
Form factor will suck though

Which reminds me, I need to make a dummy battery for my GS2 to measure power consumption.

I solved it with a external battery. But i will think about it in future.

Thanks for the answers

No wonder the Samsung Galaxy battery has such a short duration of power...If you think about it, Duo core 1.2Ghz is even STRONGER than most laptops...and their battery range ( for Laptops ) even EXEEDS 4200 mAh...and here we have a Smartphone with only 1650 mAh...Maybe its because of the bigger 15.6" screen's wattage that it has to pull...

Biggest draw in any system in the backlight for the display, phones or laptops. Secong in laptops is non-SSD hard drives while second in phones is wireless transmission (network mostly but bluetooth and wireless as well).

In terms of the battery the biggest spec you have to worry about is Voltage. most devices regulate what comes off the battery to an extent but still requires it to be within a certain range. Basically, matching is the best and definitely don't try to put a 12V battery in a spot which previously had a 3.7V battery! Unless of course you want to see some fireworks (well, atleast some smoke)! :Þ

Wow, i didnt think that anybody will look at this thread

If anybody plans to build a new battery, post it here

Also, only the lowest-power laptops are clocked at 1.2 GHz - and there's MASSIVE differences between old 1.2 GHz laptop CPUs and dual-core Cortex-A9.

TDP of an Intel SU3500 ULV is 5.5 watts - that's in addition to the motherboard chipset and GPU.

TDP of the lowest-power Core i3 is 17 watts

Atoms start at 1.2 watts for the 1.2 GHz single-core Z600 and go upwards from there. Again - add chipset and graphics to that.

Compare to, for example, OMAP4460 - the data I'm seeing indicates a max consumption of around 2.6W for the whole chip - CPU, GPU, and all onchip peripherals (typically found within the motherboard chipset on desktop systems.)

heat dissipation (phone case)

a big mistake people make a lot is charging their phones while their phone casing is on, or even using heavy apps with the phone casing on. Phone case covers the battery and increases heat dissipation thus reducing battery life quickly. take note peeps
