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

I don't understand why everyone thinks about doing stuff like this. Building batteries is best left to the professionals. They put lots of thought into the design and construction. They include temperature sensors, voltage and current so you can't overcharge, over discharge, or anything in between.

If your phone uses an in-pack fuel gauge - not worth the hassle.
Some devices, like most Samsungs, use an in-system fuel gauge - the pack has nothing but the basic protection circuits (over/undervoltage lockout, overcurrent/short protection) and sometimes an ID resistor, so if you wire in a larger battery with the same protection circuits (and possibly an ID resistor to the correct pin) it'll work.
DO NOT mess with unprotected Lithium-Ion packs or cells! It's a great way to make them go boom!
The same place giritrobbins linked SELLS prebuilt packs with protection circuitry including purpose-built chargers - http://www.adafruit.com/category/44
Getting any of these to fit in the form factor of an existing device will be next to impossible, but you can use some of the products above to make an external pack for devices that don't put fuel gauge or management circuitry into the pack (such as, as I stated before, most Samsungs).
http://www.adafruit.com/products/353 - that's a pre-matched 3-cell 18650 pack that includes all required protection circuitry. It would be electrically compatible with, for example, the battery in my Galaxy S II (other than not having NFC like my battery does, and someone would have to wire a resistor between the ID contact and ground of a dummy battery to work with a GSII.)
Bump Charge your android device
Follow the below mentioned steps so as to make the most of your battery charge:
1 Turn your device ON and Charge the device for 8 hours or more,
2 Unplug the device and Turn the phone OFF and charge for 1 hour,
3 Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour
Your battery life should almost double, as per the htc executives they have tested themselves and found out that there is a huge improvement in the battery life.
This post was published by HTC, so sharing with all android users.

Of course it's worthwhile. You can easily replace the battery if required and I'd much prefer longer usage time as I'll probably have changed phone before it's noticeable anyway. Not that I believe the method shortens the lifetime anyway.

Calibrating Li-Ion batteries is a myth...It does not hurt the battery if you don't charge it "full" before you first use it and let it drain out before its charge again...and ect...it just doesn't matter. It's all bull****.
I have never see so much voodoo related to a simple issue.
Given a device has an internal charge voltage regulator and battery voltage, current & temperature monitor, then it is possible for the system to ascertain battery full status and calibrate the monitor system with one single full charge cycle.. This is neither new nor rocket science, and has been the basis for battery monitoring systems for a very long time.
Secondly, it is quite simply not possible to overcharge a battery.. a battery of any given chemical cell structure has a voltage at capacity that is a constant. Applying higher voltages to "over-charge" a battery, simply has the excess charging power dissipated as heat in the battery charging circuit... Full = Full. Period.
all this other stuff is wishful hogwash..

This "trick" won't work on Samsung devices. It worked on HTC devices due to the type of fuel gauge chip they used, namely the ds2784 and ds2746 etc. But Samsung phones use the max17040 and max17043 fuel gauges and they do not react the same and thus "bump" charging literally does nothing on a Samsung phone.

... and then you would need to explain why managing the voltage would not manage the current ....
"could" but highly unlikely.. and tbh unless you can provide some engineering theory based substantiation for it (the voodoo), my comment stands...
fwiw, it is not actually necessary to monitor charge current... A charger, be it single stage or multi stage, applies a charge voltage and the battery accepts current. As the battery charges, so its voltage increases and when the battery voltage is raised to within a predetermined window related to the charge voltage, then that charge stage is complete.. In general the final charge cycle, float, is left running as long as the device is connected to a charging source, though in some devices (eg iphone) the float charge is cycled on and off in a tight window of battery voltage.

I do not argue with anyone, whether it is supposed to work or whether it can`t work and even not on Samsung device - whatever. Very useful and good method for me .

Thanks I'm going to try this
I think I found the way of improving the battery of tablet as in the title. The battery compartment has dimentions 126.5x67.5x5 mm.
The original battery pack is wired and of capacity ca 1800 mAh so it does not last long.
I found on eBay batteries that will fit in the battery compartment, 3 of them, and they need to be connected in parallel. That will give 5400 mAh capacity at 3.7 V. Each battery has wires and has the size of 56x36x5 mm.
Here is the link:
http://www.ebay.com.au/itm/180850958176?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
I ordered the batteries and will post further when i install and test this solution. My only concern is that the batteries connected in parallel need to have identical voltages at the moment of soldering them together (to avoid high currents between them due to different voltages which would generate heat and even could destroy them) so probably they need to be first time connected while fully discharged.

So the question is?
@UP:
It isn't forum for questions only.
@OP:
The second concern might be charging and fuel gauge, try to find out what are those ICs in your tablet, get datasheets and check if they need to have batt characteristics programmed by CPU, you might need to change parameters passed to them.
I would be very careful modifying the batteries. Li-ions have control circuitry inside of them that talk to the device and they have a very specific way they must be charge.
Even when they're used normally they have a bad habit of blowing up.

Umm, if we're talking about cellphone's batteries. No they don't (at least not in phone models I've been studying). All I've seen in this class of batteries so far is +, - and thermistor pad (and sometimes NFC Antenna), everything else is calculated by fuel gauge and charging ICs, basing on the batt parameters they get from CPU and calibration data.
The thermistor should be monitored by the device, but afaik all li-ion batteries must have control circuitry to make sure they are charged correctly. Batteries with multiple cells also need it to balance usage and charging.
Of course there's always the exception, but li-ions are by their nature unstable, so caution is still advised when doing anything with them. A quick search of YouTube shows a lot about what they're capable of.

Good day,
For the new battery owners and frequent questions of charging and prolonging/maintaining your battery.
Here are some information from other websites. Just for the sake of laziness and Google-ing :highfive:
I know most of you guys already knows this. Yes, I know. These are reminders that you should.
Please do not flame or criticize my thread. I am just here to help. Thank you!
1.) It's not necessary to charge over 12 hours when first used. When a device powered by batteries is purchased, sellers will usually tell us the batteries must first be charged 12 hours before using. Actually, this is unnecessary. Unlike common Ni-CD or Ni-MH batteries, most lithium ion batteries have been activated before leaving the factory. Due to its low self-discharge, it’s unnecessary to charge lithium ion battery for such a long time when new. Lithium ion batteries are ready for use after the charger indicates so, and it will reach its best capacity after 3 or 5 cycles
2.) Don’t use an inappropriate charger. Many people care greatly about their electronic gadgets, but often neglect the consequences of bad chargers on their lithium ion batteries. When choosing a charger, the original charger is the best choice. If that's unavailable, a high quality charger that has an over charge protection function, or a brand name charger will do. A low quality battery charger can lead to shorter run times, premature battery failure, or even cause a fire or explosion.
3.) Avoid touching metal contacts. All batteries' contacts need to be kept clean for best performance. Do not let battery contacts touch metal objects such as keys when carrying them around, it can cause a short circuit, damaging the battery or potentially resulting in a fire or an explosion.
4.) Avoid often use in high or low temperature environment. Lithium ion batteries have an optimal working and storage temperature. If they're continually used an extreme temperature environment, it will negatively affect the lithium ion battery’s use time and useful cycles.
5.) Avoid long time without use or recharge. If you don't need to use your personal electronic gadgets for a long time where the lithium ion battery might be to left unused for 3 months or more, partially recharge the lithium ion battery, then store the device (recharge the battery to around 30-70% of capacity, depending on storage time) to prevent battery damage. You may need to take the device out of storage and charge again after a few months.
6.) Avoid use lithium ion battery which is hot after being fully charged. Temperatures can be very high after the battery is freshly recharged. If you use it immediately, the electronic gadget’s internal temperature will rise, and can negatively affect the device's electronic components.

@m4xwellmurd3r
I wanted to add that I think the reason people think they need to charge the phone, then turn it off and charge it more and repeat comes from older android phones. The OG Evo was very bad with its battery stats and even if the phone was discharging it would continue to state 100% when it was plugged in. A bad cable caused my girlfriends phone to drain low enough that it couldnt be charged in the phone because the os never thought it was below 100%.
The old evo would shut off its charge circuit at 100% and kick it back on at 90%, but never show that it had discharged any. This resulted in massive percieved drain after unplugging the phone.
By charging it to 100 while on, unplugging and turning off, then charging back up while off, and repeating the process till the charging to charged indicator had a shortened delay, the battery would last longer because it calibrated not the battery, but androids internal battery states that indicated what its true 100% mark was.
But the systems ability to learn what voltages indicate 100% and 0% have become much better from what I can tell, and using that outdated method to force android to learn the min max points is now pointless.
The other issue was the old evo didnt trickle charge. From 100% it totally kicked the charge circuit off, and at 90% kicked it back on, while never reporting anything below 100% when the cable was plugged in.

Question:
If I am not going to use my battery for a long period of time, what should I do?
Answer:
Be sure the battery is above 40%
Put the battery in an air sealed zip locked bag and place it inside the refrigerator but not the freezer!
This will slow down the deterioration of the battery.

Thus, simply fully charging is good enough - overcharging will make your lithium battery into a little bomb if over charge protection function is missing.

are at odds.
I'd be interested to see your source(s) for the charging behavior of the integrated circuitry once the battery is full and the negative impacts thereof. I'm not saying that overcharging a cell isn't bad. But the battery in your phone has ic, regulating the exposure to the cell. Meaning that given that self-discharge is a characteristic of Li ion batteries, overcharge doesn't seem to be a likely concern.
Additionally, if the protection ic is in the battery, why would you need a charger with built in charge protection? This is info from hobby cells, which are bare Li ion cells. You really think the usb wall wart samsung ships you is anything more than an ac to dc, step down voltage converter? I'm open to evidence to the contrary.
The danger in Li ion is typically in in over discharge, and in charging too quickly, resulting in a cycle of increasing uncontrolled internal resistance, potentially causing combustion. The charge rate should be protected by the battery's ic, and as the battery will say it's empty before breaching the threshold of damaging discharge, it just translates to "don't leave the thing alone in a drawer for a long time with no charge", which you effectively covered.
And what's not mentioned, is that no matter what you do, no matter the obsessive charging ritual you observe, current Li ion technologies will see a roughly 10% decrease in performance per year.
Don't worry about your battery and charge it as much as you want over charge it at night. Then buy a new one a year later after that one you will have a new phone. No worries.

Normally I would agree, but some of the overcharging advice I've seen here includes charging the phone to full, then shutting it off, and letting it charge for hours longer. All in an attempt to circumvent safeguards. Weird yes, ritualistic, sure, will Samsung get blamed if the battery melts? Definitely.
Pretty good article on Lithium based batteries:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
The danger in Li ion is typically in in over discharge, and in charging too quickly, resulting in a cycle of increasing uncontrolled internal resistance, potentially causing combustion. The charge rate should be protected by the battery's ic, and as the battery will say it's empty before breaching the threshold of damaging discharge, it just translates to "don't leave the thing alone in a drawer for a long time with no charge", which you effectively covered.
And what's not mentioned, is that no matter what you do, no matter the obsessive charging ritual you observe, current Li ion technologies will see a roughly 10% decrease in performance per year.

And what you said fairly agrees with the article. (Depending on charging habits of course.)

That won't really do anything. Logically, if the phone's off, there won't be a load on the battery, thus it's free to charge at the maximum rate as controlled by the ic. But, that doesn't mean it'll end up any different at 100% from charging with the phone on.
Again I reference the fact that the battery contains the control circuitry, not the phone.

I don't recall saying anything to the contrary.

You wrote "DO NOT turn off the phone while charging" - it doesn't matter whether you do or not.
Anyway, my point was just that points 2 and 3 are wrong given the application and should be omitted as they taint the rest of the information.

At least attempt to not misquote me. It's like you argue just to argue even when in agreement.
If you don't like the thread, rate it 1 star and just keep on moving.
That simple.

I'd be interested to see your source(s) for the charging behavior of the integrated circuitry once the battery is full and the negative impacts thereof. I'm not saying that overcharging a cell isn't bad. But the battery in your phone has ic, regulating the exposure to the cell. Meaning that given that self-discharge is a characteristic of Li ion batteries, overcharge doesn't seem to be a likely concern.
Additionally, if the protection ic is in the battery, why would you need a charger with built in charge protection? This is info from hobby cells, which are bare Li ion cells. You really think the usb wall wart samsung ships you is anything more than an ac to dc, step down voltage converter? I'm open to evidence to the contrary.

I second that. Android devices en mass use integrated chargers and protected batteries. In that case using cheap charger could possibly demage buildin charger rather than battery itself.
And almost all wall chargers for phone and tablets are simple power source. An modern one with ac-dc IC regulators but still act as ordinary power source.

Don't worry about your battery and charge it as much as you want over charge it at night. Then buy a new one a year later after that one you will have a new phone. No worries.

I agree 100%.
Although most advices in the OP are correct I don't agree there is a thing like "overcharging" - there is a circuity to prevent charging when the battery is fully charged.
So avoid myths, just use your device, batteries are not that expensive

We all know how important batteries are in our modern electronics. They’re also becoming an increasingly vital part of our vehicles. For people in both camps, the latest news from Toyota is disheartening: Li-Ion batteries have a “memory effect”.
Ni-Cad Batteries
When the traditional, land-line telephone evolved from a corded beast into a clunky — but wireless — beast, there was much cause for celebration. The battery technology of the day was Ni-Cad (Nickel Cadmium). Batteries based on this technology were used in everything from cordless phones to satellites orbiting the planet. There were two significant problems that plagued these batteries.
First, after thousands of charge/discharge cycles to within 2% of the same state of charge, the battery would develop a “sudden drop” in voltage. To many electronic devices, this drop would make the battery appear “dead”. NASA figured this one out because their batteries could only be charged when the sun was shining on panels, and the satellites usually used the same amount of energy to power them while they were in Earth’s shadow. It’s extremely unlikely that any consumer electronic device would be subjected to conditions that would reproduce this problem. Scientists at GE’s Battery Business Department in Gainesville, Florida published a paper describing the “memory effect”, but didn’t convey that Earth-bound consumers should never run into this condition, and later retracted their paper, but the damage in the public-eye was already done.

What kind of battery technology powers V’GER?
Second, there was another issue with Ni-Cad batteries that presented symptoms similar to that discovered by NASA and GE: “voltage depression” or “lazy battery effect”. This results from repeated overcharging, but can generally be “fixed” by subjecting the battery to a few deep cycles.
Eventually new technologies were introduced, eventually bringing us to today’s Li-Ion and Li-Polymer batteries. Unfortunately, to the typical end-user who wants their electronics to be fully-charged, keeping the battery on the charger for extended periods of time only increases the effect, and makes the usable per-charge lifespan of the battery lower — even with the new technology.
Li-Ion Batteries
Lithium Ion and Lithium Polymer batteries are found in almost every electronic device today. Cell phones, smart watches, and even hybrid and electric vehicles are powered by these technological gems. According to a new study, even our latest and greatest battery technology isn’t immune from the dreaded “memory effect”, though you’re not as likely to see it as you were with Ni-Cad batteries. That’s the good news.
Samsung Li-Ion Battery
The battery inside your cell phone is likely Li-Ion
There’s a lot of physics and technical information behind why batteries present this “memory” when discharging, and if you’re interested in all that, I highly recommend the article at Phys.org that I’ve linked below. For this article, however, suffice it to say that Li-Ion has the same problem as older battery technologies, just not as visible. Luckily, the “solution” is the same today as it was two decades ago.
How to Defeat the Memory Effect of Li-Ion Batteries
We’ve all got to realize that we can’t get rid of the “memory effect” problem. It’s inherent to the technology — and likely to batteries in general. But now that we know about it, we can adapt and minimize the impact the “memory effect” has on our electronics. It’s fairly simple, which may be one reason why it’s not widely adopted. Keep the following rules in mind:
Realize that your batteries don’t like to live at the very top or the very bottom of their charge capacity. Don’t keep your devices on the charger after they’re fully charged. Similarly, don’t leave them dead in a drawer for expended periods of time either.
Every once in a while, completely discharge your device, then completely charge it up again. Do that a few times in a row. This will help “condition” the battery and will ensure that you get better use of its capacity. Doing this will reduce the rated lifespan of the battery, but it will get you more practical use out of it and prevent a premature death.
That’s it. Pretty simple, right? Ironically that’s what HAM Radio operators have been telling us for many decades, and those guys really know their stuff!

that video's 28 minutes long! if the op takes you longer then you may not really need to be in a tech oriented forum, lol.:laugh::angel:
That's awesome that they can confirm something most people already knew.
