I have owned plenty of cellular phones over the last few years, as I am sure everyone has, and while none have been especially amazing, some have definitely been crap. The only problem I have ever had with my cell phones has been with the cell battery. The cell phone battery has either died or it just would not last long enough and I would need to buy and carry a replacement battery.
I do use my mobile phone a lot, both for my work and for personal use, so having another battery is often a good idea but having to replace a faulty or damaged battery is annoying. My latest phone is working well but I would like a replacement battery for those times when I am not in the office.
Cell Phone Battery
These are the details of my current phone (yep, I know it is a bit obsolete, I really should buy a new cell phone):
Samsung SPH-A420
Positives:
The Samsung SPH-A420 is easy to use and offers a speakerphone, analog roaming, and acceptable call quality.
Negatives:
The Samsung SPH-A420 has a dull, uninspiring design and lacks such basic features as an external display and a wireless Web browser.
Facts:
The Samsung SPH-A420 is a serviceable phone for making calls, but it has an unattractive design and few features.
As cell phones transition from communication devices to fashion accessories, even basic models aim to appeal to the style conscious. Even if it’s as a simple as a choice of colors, functional handsets, such as the Sanyo SCP-2400, are trying to stand out. That’s why it’s becoming more surprising to see phones like the Samsung SPH-A420 for Sprint. Not only is its design uninspired, it’s downright boring and reminiscent of the first flip phones from a few years ago. You won’t find a lot under the hood either, as the features reflect the minimalist style. However, as a phone for making calls, the SPH-A420 gets the job done.
From the outset, you can see that the SPH-A420 won’t win any beauty contests. Completely straight lines and sharp corners give it an almost perfectly rectangular shape, while the silver color and black band won’t catch envious looks on the street. On the upside, the phone is compact (3.4 by 1.7 by 0.8 inches) and lightweight (2.9 ounces), so it slips easily into a pocket and won’t weigh you down. Also, the construction is solid, and we felt comfortable holding the phone while talking. We’re surprised, however, that phone manufacturers are continuing to pump out models without external displays. We realize it may save a few dollars, but that means you must open the SPH-A420 to see your caller’s identity.
Like its feature set, the SPH-A420’s design is truly basic.
Flip open the mobile, and you’ll find a standard Samsung internal display. Measuring 1.6 inches diagonally (128×160 pixels) and supporting 65,000 colors, it’s quite serviceable for a phone of this caliber. Colors are sharp and the screen bright. You can change the backlighting time and the dialing font size and color, but other screen-editing options are not available. Also, like the Samsung SPH-A640, it’s one of the first handsets to support Samsung’s new menu designs.
The SPH-A420’s navigation array has a typical Samsung design. A four-way toggle surrounds a central OK button and doubles as a shortcut to four user-defined functions. The other controls included two soft keys, the talk and end/power buttons, and a back key. There’s also a dedicated speakerphone key, which is a nice touch. The keypad buttons are flat with the surface of the phone, so it’s somewhat hard to dial by feel. They’re decently sized, though, and they benefit from a bright backlighting. The only exterior features are a volume rocker and a covered headset jack on the left spine and a tiny green light on the front flap that blinks for incoming calls.
The SPH-A420’s feature set is minimal, but keep in mind simplicity is the overall theme here. The phone book holds 300 contacts with room in each entry for four phone numbers, an e-mail address, and a memo. You can organize callers into groups or pair them with one of 10 monophonic or 35 40-chord polyphonic ring tones. You can assign a photo, but since the SPH-A640 doesn’t have a camera or a Web browser and doesn’t support multimedia messaging, you’re out of luck if you don’t like the preloaded graphics. Other features include a task list, a scheduler, an event reminder, a countdown timer, a memo pad, a world clock, a calculator, an alarm clock, and text messaging. Voice features include voice memos and dialing a speakerphone that you can activate before you make a call. Strangely, there’s an airplane mode, but we can’t imagine why you’d want to use it.
You can personalize the SPH-A640 with a variety of screensavers, greetings, and alert sounds. But there’s no wireless Web browser, so you’re stuck with the options already on the phone. You don’t get any games either.
We tested the dual-band, dual-mode Samsung SPH-A420 in San Francisco using Sprint’s service. Call quality was good overall, though voices on our end sounded a bit tinny. Callers reported the same conditions, but they weren’t bothered too much. The volume level was satisfactory as well, but we had a bit of trouble understanding our friends in very noisy environments. Speakerphone quality was about the same; calls were audible and noisy on our end, but callers usually asked that we switch to a normal call.
The SPH-A420 has a rated talk time of 3.5 hours, which we met in our tests. Our standby battery test came to 11.5 days. According to FCC radiation tests, the Samsung SPH-A420 has a digital SAR rating of 1.32 watts per kilogram.
So I suppose the right question is do I spend the money buying a new Samsung SPH-A420 cellular phone battery or do I just get a new phone with a long lasting battery? Replacement batteries are reasonably inexpensive but a new phone would be good too. I must make a decision…
