[BATTERY REVIEW] ECell Gold 2430 mAh Lithium Polymer Battery
Well I arrived home from some boxing day shopping today to a package in the mail from ECell in England. Sound like a similar tale from two weeks ago? Yup! It's another battery review and test. Second week results of my previous test of the Cameron Sino Technology 2200 mAh Lithium Ion "FAT" Battery are now posted in the review thread so check those out as well. so back to my initial thoughts. The battery came encased in a simple thin plastic deliver bag with no protection around the battery. Sorry ECell but taking the slow boat from China (Literally) I would expect a little more protection. So...5 points off for shipping style. What was fairly impressive was the time to ship from England to Canada less the days the post was closed for weekends and holidays totalled 7 business days. So...5 points back for delivery as promised. The battery is currently doing it's initial charge on the universal charger before I pop it in, clear my stats and start testing. The first thing I can say about it is...Wow...Shiny. I like shiny things. :P Aesthetics aside, it fits properly, nice and snug under the original rear housing. I will have to get used to a "thin" phone again at least for a while... Ok. Prediction time... I don't see this battery making 2430 mAh but who knows. Li-Pol is different stuff and hopefully it's what slim dreams are made of. For $17.00 US, including shipping, I won't complain if it hits 1700-1800 mAh but here's hoping. Attached are some photos of the HTC Stock, The Cameron Sino Technology and the ECell batteries side by each and parallel for your enjoyment and viewing pleasure. :P Notice the dimensional similarities between the stock and the ECell. I don't have my scales of power and wisdom handy so I was unable to weigh the batteries but it feels slightly lighter to the touch but not by a considerable amount. Right now it is at 3.85 volts and rising and very cool to the touch. Once it's done it's initial charge I am going to run it dry under normal use a few times to calibrate the battery and post the results for average longevity, coolness to the touch during use, charging, and charge while using. I will also post the calibrated mAh reading as well as any temperature fluctuations, etc. | |

Usage and test results...
2011-12-31: -Battery took 4 hours to charge up to 4.218 volts -Estimated full from empty AC charge is 4.5 hours -No heat generation to speak of during charging or use so far. 2012-01-02: -Battery has been charged and fully discharged 3 times now. Reset all stats and running an Antutu Battery Test on it that I will also run on the stock and CS 2200 mAh to have some comparisons that mean something. Testing setup is as follows: -Same phone with CM7.2 overclocked to 806 mhz to speed up the testing process for all three batteries -Batteries all conditioned and then charged for 8 hours prior to testing -No changing of configured apps, services, etc on phone during testing -batterystats.bin and Battery Monitor Pro history is wiped between batteries -Wifi and data turned off so the phone does essentially nothing -Antutu stops phone from locking, dimming, downclocking etc. so it's basically running all out for the entire duration -No one seems to know what the scores are or how they relate to anyone else but I figure they will relate to each other. -Once test is complete run Antutu again to run the battery down to 1% for shutdown and get final burn time results from Battery Monitor Pro TEST 1: ECell Gold 2430 mAh replacement battery Test start time: 03:03 AM Test start %: 100% Test end time: 06:40 AM Test end %: 19% Antutu Test duration: 03:37 Rundown end time: 07:22 AM Rundown end %: 1% Total test duration: 4:19 Test score: 652   TEST 2: HTC 1230 mAh stock battery Test start time: 12:58 PM Test start %: 100% Test end time: 03:48 PM Test end %: 19% Antutu Test duration: 03:00 Rundown end time: 4:32 PM Rundown end %: 1% Total test duration: 03:44 Test score: 508   TEST 3: Cameron Sino 2200 mAh replacement battery Test start time: 05:10 PM Test start %: 100% Test end time: 11:31 PM Test end %: 19% Antutu Test duration: 06:21 Rundown end time: 12:45 AM Rundown end %: 1% Total test duration: 07:35 Test score: 1145   Final Results For ECell Gold, HTC Stock, and Cameron Sino: -3 Hours and 44 Minutes For HTC Stock Battery -4 Hours and 19 Minutes For ECell Gold Battery -7 Hours and 35 Minutes For Cameron Sino Battery -The ECell Gold, at 13.34% more capacity than the HTC Stock battery, comes in at far less than it's advertised 2430 mAh. -The Cameron Sino, at 50.52% more capacity than the HTC Stock battery, comes in at more than it's advertised capacity of 2200 mAh The Conclusion: You can't make a silk purse out of a sow's ear and you can't cheat physics. Applying the same battery technology you can really only expect marginal performance gains in the same form factor as is shown with the underachievement of the ECell Gold compared to it's advertised capacity. There were no surprises here. Double the form factor brought double the capacity. If you're cool with a "Fat Phone", the Cameron Sino Technology 2200 mAh battery lives up to it's expectations and puts some reality back into things. You get a very high capacity battery at a very reasonable $22.00 US In it's own right the ECell Gold 2430 mAh is a great idea for a cheap and higher capacity replacement battery and that's really the positive in that storyline. The price is right for a slim replacement battery but they need to stop the gimmickry and advertise it for what it is. False hope is NOT better than no hope.
